TITLE: Ultrastable optical reference cavity system for 1396 nm Requesting Lab/Division/Group: PML / 688 / 688.60

General Statement of Need We are required to purchase an ultrastable optical reference cavity system with operating wavelength of 1396 nm for our quantum sensing project, which is developing and exploring a strontium optical lattice clock with integrated photonics.

Items and/or Ancillary Services

Item 1: 1396 nm optical frequency reference cavity system Quantity: 1 Specifications: 1.1 Ultrastable reference cavity system with thermal noise fractional frequency stability of 6x10^(-16), enabling a stabilized laser linewidth less than 1 Hz.

1.2 Primary Operating wavelength of 1396 nm with a finesse of 200,000 to 400,000

1.3 Secondary operating wavelength of 689 nm with a finesse of 1,000 to 20,000

1.4 AR coating with less than 0.1% reflection at primary and secondary operating wavelengths

1.5 Must accommodate operating temperature in laboratory of 24 deg C

1.6 Vacuum housing with invar mounting block and positioned viton balls for low vibration stability

1.7 Temperature control at the cavity inside shielding must be <1 mK/day

1.8 Heaters and thermistors for temperature control must be included

1.9 The thermal time constant must be approximately 38 hours, to ensure sufficient thermal isolation from the room temperature environment and so equilibration time after a temperature change will be ~200 hours.

1.10 Vacuum housing windows must be AR coated at the primary and secondary operating wavelengths

1.11 The cavity housing will be tunable to the zero-crossing temperature of the cavity.

1.12 The vendor will provide a measurement and characterization of the zero crossing temperature of the optical reference cavity. The zero crossing temperature will be suitable for operation in a laboratory temperature of 24 deg C. The zero crossing temperature of the optical reference cavity must be in the range of 28 to 40 deg C.

1.13 Temperature controller will be included and the temperature controller will be tuned to control the vacuum housing of the cavity system.

1.14 Ion pump, cable, and controller and vacuum valve will be provided for the vacuum enclosure of the cavity system

1.15 Vendor must report necessary laboratory operating conditions to achieve specified performance

1.16 Ultrastable reference cavity system must enable laser stabilization to a modified Allan deviation at 1550 nm of 6x10^(-16) at 1 second averaging time.

1.17 Less than 15 kHz/day at 1550 nm equivalent near zero crossing

1.18 Less than 1x10^(-10)/g fractional acceleration sensitivity along all axes
