MINIMUM REQUIREMENTS FOR A

DIVERSE WAVELENGTH TUNABLE RING LASER SYSTEM

2018 JUNE 10

GENERAL

AFIT’s current inventory of ring lasers stems are aging, with the newest ring laser in inventory being over 10 years old, AFIT has no current technology ring lasers to perform laser spectroscopy experiments. This new ring laser system is required to conduct spectroscopy experiments over an extremely wide range of effective wavelengths with unprecedented precision and would effectively replace, and dramatically add to current capabilities in the laboratory.

This specification lists the minimum requirements for the diverse wavelength tunable ring laser system:

(1) Power: The core titanium sapphire ring laser must achieve at least 4 Watts of peak output power between wavelengths of 700-1,000 nm, and at least 100 mWatts of peak power between 515-660 nm range, at least 50 mWatts of peak power between 302-347 nm range, at least 1 W of peak power in the 350-500 nm range, and at least 10 mWatts in the

210-250 nm range.

(2) Size: The system must be compact to allow for additional equipment in the operational environment – the core titanium sapphire ring laser should be smaller than 30 x 18 x 10 cm.

(3) Environment Immunity: The core titanium sapphire ring laser must be hermetically sealed to prevent dust from entering the cavity while simultaneously allowing for purge times of less than 10 minutes.

(4) Robustness: The core titanium sapphire ring laser surviving environment trauma (for example, drops from heights of at least 1 m, extreme vibration, or similar) must be demonstrated.

(5) Demonstrated Performance: A list of existing customers using the ring laser system must be provided with contact information to demonstrate prior performance.

(6) Remote Operation: The core titanium sapphire ring laser must have no manually adjustable parts that require human intervention while still being fully tunable from 700 to 1,000 nm with software development kits available in LabView and Python.

(7) Scanning Parameters: The core titanium sapphire ring laser must have scan rates of up to

200 GHz/sec with mode-hop free wavelength scanning over 5 nm with up to 10 kHz resolution in less than 10 minutes. High resolution single scan widths must be at least 25

GHz wide.

(8) Amplitude Noise: The core titanium sapphire ring laser must have an amplitude noise of

0.1% RMS or better.

(9) Linewidth: The core titanium sapphire ring laser must have an absolute linewidth of 50

KHz or better.

(10) Wavelength Access: Additional modules must allow for tunability over the spectral ranges of 210-250 nm, 302-347 nm, 350-500 nm, 515-660 nm, and 700-1,000 nm.

(11) Visible Frequency Doubling Mechanism: The core titanium sapphire ring laser must be coupled to a visible frequency doubled for the range of 350-500 nm and must achieve at least 35% conversion efficiency. The frequency doubling cavity must not need temperature control.

(12) Pump Source: The laser system must include a single mode Verdi V18 as the pump source to support mixing modules.

(13) Chillers: The laser system must include any chillers needed to support all normal operations.

(14) Mixing sources: The laser system must include all pump sources required for mixing to achieve all tunable ranges.

(15) Wavemeter: The laser system must give a wavelength reference using a wavemeter for fast feedback of the laser output with resolution and sample speed equal to or better than a High Finesse WS-6. The wavemeter must also include all optics for coupling and integrate with the ring laser control software to support wavelength estimates for all tunable wavelength ranges listed.

(16) Laser Dye: The laser system must not contain or require any laser dye or laser dye medium for operation at any wavelength.

(17) Control System: The laser system must include all hardware, firmware, software, and computer systems needed for operation.

(18) Documentation: Full documentation for maintaining, operating, and repairing the laser system, including all control software, must be included.

(19) Updates: Future software updates will be made available to AFIT as they become available free of additional charges.

(20) Installation & Training: The complete laser system must be installed in AFIT’s laboratory and the manufacturer must provide hands on training for all operation and maintenance of the laser system (for example, the training traditionally given to new field technicians). A complete user guide for all operations must be included. A complete maintenance manual for all repairs must be included.

PERIOD OF PERFORMANCE

The customer will receive all components 6 months after contract award.

DELIVERY AND TRAINING

The contractor will deliver hardware to the Air Force Institute of Technology (AFIT) at WPAFB, OH and will allow for two days of installation and three days of training on site for a minimum of four AFIT personnel.

WARRANTY

Laser system must be free from defects in material and workmanship, under normal and proper use in accordance with our instructions in the maintenance manual, for the period of time of one year after receipt.

PAYMENTS

"100% payment (IAW Wide Area Workflow procedures) after completion of delivery, installation, and training."
