STATEMENT OF WORK (SOW)

Strontium Optical Lattice Clock Laser System for the United States Naval Observatory

1.0 REQUIREMENTS

The contractor shall provide to the Government products and services meeting the specifications detailed within this SOW.

The Clock Development Division at the U.S. Naval Observatory (USNO) is beginning a project to build a laboratory prototype of an optical-lattice clock using strontium (Sr). The USNO hopes to build a system that is capable of reaching performance of about 1015 at 1s and integrating down close to 10-18. The contractor shall provide to USNO a laser system for this project that will provide all of the laser light that is required to fully make and operate a Sr optical lattice clock, using either 87Sr or 88Sr, with this desired performance. This system shall include the frequency comb and all required continuous-wave (CW) lasers, including the narrow linewidth clock laser, lasers for two stages of laser cooling, lasers required for repumping during laser cooling and for measuring the excited clock state population, and the optical lattice laser.

The system shall be “turn-key” – robust, reliable, and continuously operating without user intervention. The required specifications for this system are as follows:

1.1 CW LASER SYSTEM

The contractor shall furnish to the Government a laser system that will provide all of the CW laser light required to make and operate a Sr optical-lattice clock with 1s stability characterized by an Allan deviation of 11015 or better. More specifically, the system shall meet the following minimum requirements with regard to components and performance.

1.1.1 Clock Laser

· Wavelength: 698.4 nm.

· Specifically, the source laser wavelength must be resonant with the 1S0-3P0 698-nm clock transition in 87Sr (and must be able to be tuned to the same transition in 88Sr). At the clock wavelength for either isotope, the source laser must be able to be tuned continuously over 10 GHz without mode-hopping. If this tuning spec cannot be met, provide a guaranteed mode-hop free tuning range around the clock frequency for consideration.

· Linewidth of 1 Hz or better by locking to a high-finesse cavity;

· In particular, the narrowed clock laser must support a frequency stability of 11015 at 1s or better; a stability of 51016 at 1s is preferable, but not at the expense of robust and reliable operation. A stability of 21015 is not acceptable. This performance must be achievable in a standard laboratory environment.

· Ideally, when locked to the cavity, the laser frequency should be between 80 MHz and 500 MHz away from the 87Sr clock transition.

· The source laser must stay locked to the cavity “24/7” (24 hours per day, 7 days per week), without user intervention, for weeks at a time in a conventional laboratory environment (where temperature/humidity changes can occur). Relocking the system must be a routine procedure for the end user.

· Fiber coupled output, with linear polarization aligned with the slow axis of the PM fiber and with the fiber connector key.

· The fiber length should be between 1m and 3m.

· The fiber-induced phase noise must be actively cancelled so that the same linewidth is realized at the fiber output as at the input.

· Ideally, a mechanism will be incorporated to enable shifting of the clock laser frequency that could be used to remove the drift of the cavity or to lock the laser to an atomic transition.

· Useable power out of fiber: ~10 mW

1.1.2 First-stage cooling laser

· Wavelength: 460.9 nm

· Specifically, this laser must be resonant with the 1S0-1P1 461 nm laser cooling transition in 87Sr (and tunable to the same transition in 88Sr).

· Linewidth: 1 MHz or less

· Fiber coupled output, with linear polarization aligned with the slow axis of the PM fiber and with the fiber connector key.

· Useable power out of fiber: 400 mW

· This suggests a frequency-doubled system

1.1.3 Second-stage cooling laser

· Wavelength: 689.3 nm

· Specifically, this laser must be resonant with the 1S0 (F=9/2) - 3P1 (F=11/2) transition in 87Sr (and tunable to the same transition in 88Sr) for narrow-line laser cooling.

· Linewidth: 100 Hz; max. 500 Hz.

· This laser must support cooling of strontium atoms to temperatures of about 1K

· Fiber coupled output, with linear polarization aligned with the slow axis of the PM fiber and with the fiber connector key.

· Useable power out of fiber: 10 mW

· Ideally, we would like a mechanism for generation of a “stirring” laser, resonant with the 1S0 (F=9/2) - 3P1 (F=9/2) transition, about 1.5GHz higher in frequency.

1.1.4 Repump laser 1

· Wavelength: 707.2 nm

· Specifically, this laser must be resonant with the 3P0-3S1 transition in strontium for repumping atoms during laser cooling and measurement of the excited clock state population

· Linewidth: 200 kHz

· Fiber coupled output, with linear polarization aligned with the slow axis of the PM fiber and with the fiber connector key.

· Useable power out of fiber: 10 mW

1.1.5 Repump laser 2

· Wavelength: 679.3 nm

· Specifically, this laser must be resonant with the 3P2-3S1 transition in strontium for repumping atoms during laser cooling and measurement of the excited clock state population

· Linewidth: 200kHz

· Fiber coupled output, with linear polarization aligned with the slow axis of the PM fiber and with the fiber connector key.

· Useable power out of fiber: 10 mW

1.1.6 Lattice laser

· Wavelength: 813.4 nm

· Specifically, this laser must be tuned to the “magic” wavelength for trapping strontium in an optical lattice without first-order AC Stark shifts

· Linewidth: 200 kHz

· Ideally, if the laser uses a semiconductor amplifier, it should include 1 nm bandpass filter to reduce deleterious amplified spontaneous emission.

· Fiber coupled output, with linear polarization aligned with the slow axis of the PM fiber and with the fiber connector key.

· Useable power out of fiber: 1W

· Please make the lattice laser a separate line item in the system quote.

1.1.7 Other

· Frequency stability: all CW lasers shall be frequency stabilized. This can be via reference cavities, frequency comb lines, vapor cells or another technique. The locks shall be robust and reliable.

· All locking electronics, beat-note detection systems, photodetectors and other equipment required to make and monitor these locks shall be included.

· All optical isolators required to use the CW lasers and achieve specified performance shall be included.

· User-serviceable spare laser diodes for any ECDLs used in the system shall be provided.

· The system shall be as integrated and compact as possible, without sacrificing robustness. Having at least some of the less critical laser systems rack-mounted would be desirable. Since this is a difficult property to specify precisely, the USNO includes it not as a requirement but rather as something that should be considered when comparing cost of different systems.

1.2. FREQUENCY COMB SYSTEM

· The frequency comb should be based on a fiber laser oscillator

· The frequency comb shall support a stability at 1s of 1016 or better and a floor of 1018 or better

· The frequency comb shall have an optical output at 689.3 nm for locking to the CW clock laser discussed above. The frequency comb shall be able to easily, routinely, robustly lock to the CW clock laser.

· The laser shall have enough power per comb mode to support a beat note with 100W from the stabilized clock laser of 30 dB.

· An output port for the mode-locked oscillator must be provided, allowing us to implement our own RF/microwave generation.

· The system shall have an RF output at the laser repetition rate (or multiple thereof), and preferably an output at 5MHz as well.

· All servos, beat-note detection systems, etc., to enable a lock to a CW laser at 689.3 nm and generate a stabilized RF/microwave output shall be provided.

· This system shall be turn-key and operate reliably without user intervention for weeks at a time.

1.3 ADDITIONAL INFORMATION

· The system shall include all oscilloscopes and spectrum analyzers required for routine, daily operation and monitoring.

· All of the specifications shall be achievable in a standard laboratory environment.

· The system shall be turn-key. The contractor shall install the system in the USNO laboratory in Washington, DC. The contractor shall provide training to the Government on the system’s use.

The prices included in this contract include the prices of the products/services requested as well as all ancillary costs associated with fulfilling the Government’s requirements (e.g., shipping, handling, etc.).

2.2 INFORMATION TECHNOLOGY

THE FOLLOWING NAVSUP LOCAL TEXT IS HEREBY MADE PART OF THE STATEMENT OF WORK/PERFORMANCE WORK STATEMENT.

Contractor Unclassified Access to Federally Controlled Facilities, Sensitive Information, Information Technology (IT) Systems or Protected Health Information

Homeland Security Presidential Directive (HSPD)-12, requires government agencies to develop and implement Federal security standards for Federal employees and contractors. The Deputy Secretary of Defense Directive-Type Memorandum (DTM) 08-006 – “DoD Implementation of Homeland Security Presidential Directive – 12 (HSPD-12)” dated November 26, 2008 (or its subsequent DoD instruction) directs implementation of HSPD-12. This clause is in accordance with HSPD-12 and its implementing directives.

APPLICABILITY

This text applies to contractor employees requiring physical access to any area of a federally controlled base, facility or activity and/or requiring access to a DoN or DoD computer/network/system to perform certain unclassified sensitive duties. This clause also applies to contractor employees who access Privacy Act and Protected Health Information, provide support associated with fiduciary duties, or perform duties that have been identified as National Security Position, as advised by the command security manager. It is the responsibility of the responsible security officer of the command/facility where the work is performed to ensure compliance.

Each contractor employee providing services at a Navy Command under this contract is required to obtain a Department of Defense Common Access Card (DoD CAC). Additionally, depending on the level of computer/network access, the contract employee will require a successful investigation as detailed below.

ACCESS TO FEDERAL FACILITIES

Per HSPD-12 and implementing guidance, all contractor employees working at a federally controlled base, facility or activity under this clause will require a DoD CAC. When access to a base, facility or activity is required contractor employees shall in-process with the Command’s Security Manager upon arrival to the Command and shall out-process prior to their departure at the completion of the individual’s performance under the contract.

ACCESS TO DOD IT SYSTEMS

In accordance with SECNAV M-5510.30, contractor employees who require access to DoN or DoD networks are categorized as IT-I, IT-II, or IT-III. The IT-II level, defined in detail in SECNAV M-5510.30, includes positions which require access to information protected under the Privacy Act, to include Protected Health Information (PHI). All contractor employees under this contract who require access to Privacy Act protected information are therefore categorized no lower than IT-II. IT Levels are determined by the requiring activity’s Command Information Assurance Manager.

Contractor employees requiring privileged or IT-I level access, (when specified by the terms of the contract) require a Single Scope Background Investigation (SSBI) or T5 or T5R equivalent investigation, which is a higher level investigation than the National Agency Check with Law and Credit (NACLC)/T3/T3R described below. Due to the privileged system access, an investigation suitable for High Risk national security positions is required. Individuals who have access to system control, monitoring, or administration functions (e.g. system administrator, database administrator) require training and certification to Information Assurance Technical Level 1, and must be trained and certified on the Operating System or Computing Environment they are required to maintain.

Access to sensitive IT systems is contingent upon a favorably adjudicated background investigation. When access to IT systems is required for performance of the contractor employee’s duties, such employees shall in-process with the Navy Command’s Security Manager and Information Assurance Manager upon arrival to the Navy command and shall out-process prior to their departure at the completion of the individual’s performance under the contract. Completion and approval of a System Authorization Access Request Navy (SAAR-N) form is required for all individuals accessing Navy Information Technology resources. The decision to authorize access to a government IT system/network is inherently governmental. The contractor supervisor is not authorized to sign the SAAR-N; therefore, the government employee with knowledge of the system/network access required or the COR shall sign the SAAR-N as the “supervisor”.

The SAAR-N shall be forwarded to the Command’s Security Manager at least 30 days prior to the individual’s start date. Failure to provide the required documentation at least 30 days prior to the individual’s start date may result in delaying the individual’s start date.

When required to maintain access to required IT systems or networks, the contractor shall ensure that all employees requiring access complete annual Information Assurance (IA) training, and maintain a current requisite background investigation. The Contractor’s Security Representative shall contact the Command Security Manager for guidance when reinvestigations are required.

INTERIM ACCESS

The Command's Security Manager may authorize issuance of a DoD CAC and interim access to a DoN or DoD unclassified computer/network upon a favorable review of the investigative questionnaire and advance favorable fingerprint results. When the results of the investigation are received and a favorable determination is not made, the contractor employee working on the contract under interim access will be denied access to the computer network and this denial will not relieve the contractor of his/her responsibility to perform.

DENIAL OR TERMINATION OF ACCESS

The potential consequences of any requirement under this clause including denial or termination of physical or system access in no way relieves the contractor from the requirement to execute performance under the contract within the timeframes specified in the contract. Contractors shall plan ahead in processing their employees and subcontractor employees. The contractor shall insert this clause in all subcontracts when the subcontractor is permitted to have unclassified access to a federally controlled facility, federally-controlled information system/network and/or to government information, meaning information not authorized for public release.

CONTRACTOR’S SECURITY REPRESENTATIVE

The contractor shall designate an employee to serve as the Contractor’s Security Representative. Within three work days after contract award, the contractor shall provide to the requiring activity’s Security Manager and the Contracting Officer, in writing, the name, title, address and phone number for the Contractor’s Security Representative. The Contractor’s Security Representative shall be the primary point of contact on any security matter. The Contractor’s Security Representative shall not be replaced or removed without prior notice to the Contracting Officer and Command Security Manager.

BACKGROUND INVESTIGATION REQUIREMENTS AND SECURITY APPROVAL PROCESS FOR CONTRACTORS ASSIGNED TO NATIONAL SECURITY POSITIONS OR PERFORMING SENSITIVE DUTIES

Navy security policy requires that all positions be given a sensitivity value based on level of risk factors to ensure appropriate protective measures are applied. Contractor employees under this contract are recognized as Non-Critical Sensitive [ADP/IT-II] positions when the contract scope of work require physical access to a federally controlled base, facility or activity and/or requiring access to a DoD computer/network, to perform unclassified sensitive duties. This designation is also applied to contractor employees who access Privacy Act and Protected Health Information (PHI), provide support associated with fiduciary duties, or perform duties that have been identified as National Security Positions. At a minimum, each contractor employee must be a US citizen and have a favorably completed NACLC or T3 or T3R equivalent investigation to obtain a favorable determination for assignment to a non-critical sensitive or IT-II position. The investigation consists of a standard NAC and a FBI fingerprint check plus law enforcement checks and credit check. Each contractor employee filling a non-critical sensitive or IT-II position is required to complete:

Failure to provide the required documentation at least 30 days prior to the individual’s start date shall result in delaying the individual’s start date. Background investigations shall be reinitiated as required to ensure investigations remain current (not older than 10 years) throughout the contract performance period. The Contractor’s Security Representative shall contact the Command Security Manager for guidance when reinvestigations are required.

Regardless of their duties or IT access requirements ALL contractor employees shall in-process with the Command’s Security Manager upon arrival to the command and shall out-process prior to their departure at the completion of the individual’s performance under the contract. Employees requiring IT access shall also check-in and check-out with the Navy Command’s Information Assurance Manager. Completion and approval of a System Authorization Access Request Navy (SAAR-N) form is required for all individuals accessing Navy Information Technology resources. The SAAR-N shall be forwarded to the Navy Command’s Security Manager at least 30 days prior to the individual’s start date. Failure to provide the required documentation at least 30 days prior to the individual’s start date shall result in delaying the individual’s start date.

The contractor shall ensure that each contract employee requiring access to IT systems or networks complete annual Information Assurance (IA) training, and maintain a current requisite background investigation. Contractor employees shall accurately complete the required investigative forms prior to submission to the Command Security Manager. The Command’s Security Manager will review the submitted documentation for completeness prior to submitting it to the Office of Personnel Management (OPM); Potential suitability or security issues identified may render the contractor employee ineligible for the assignment. An unfavorable determination is final (subject to SF-86 appeal procedures) and such a determination does not relieve the contractor from meeting any contractual obligation under the contract. The Command’s Security Manager will forward the required forms to OPM for processing. Once the investigation is complete, the results will be forwarded by OPM to the DoD Central Adjudication Facility (CAF) for a determination.

If the contractor employee already possesses a current favorably adjudicated investigation, the contractor shall submit a Visit Authorization Request (VAR) via the Joint Personnel Adjudication System (JPAS) or a hard copy VAR directly from the contractor’s Security Representative. Although the contractor will take JPAS “Owning” role over the contractor employee, the Command will take JPAS "Servicing" role over the contractor employee during the hiring process and for the duration of assignment under that contract. The contractor shall include the IT Position Category per SECNAV M-5510.30 for each employee designated on a VAR. The VAR requires annual renewal for the duration of the employee’s performance under the contract.

BACKGROUND INVESTIGATION REQUIREMENTS AND SECURITY APPROVAL PROCESS FOR CONTRACTORS ASSIGNED TO OR PERFORMING NON-SENSITIVE DUTIES

Contractor employee whose work is unclassified and non-sensitive (e.g., performing certain duties such as lawn maintenance, vendor services, etc. ...) and who require physical access to publicly accessible areas to perform those duties shall meet the following minimum requirements:

To be considered for a favorable trustworthiness determination, the Contractor’s Security Representative must submit for all employees each of the following:

The contractor shall ensure each individual employee has a current favorably completed National Agency Check with Written Inquiries (NACI) or T1 equivalent investigation, or ensure successful FBI fingerprint results have been gained and investigation has been processed with OPM

Failure to provide the required documentation at least 30 days prior to the individual’s start date may result in delaying the individual’s start date.

* Consult with your Command Security Manager and Information Assurance Manager for local policy when IT-III (non-sensitive) access is required for non-US citizens outside the United States.
