1033 nm and 1068 nm Lasers for Reimagining Thermal Radiation Combined Sources

THIS IS A COMBINED SOURCES SOUGHT NOTICE AND NOTICE OF INTENT TO SOLE SOURCE.

BACKGROUND The Fundamental Thermodynamics group is developing molecule laser cooling platform that will enable advanced pressure and temperature metrology. This project requires a robust, spectrally narrow source of laser light to detect the molecule yield from a cold molecular beam source. This light source must be tunable for wavelengths from 1033.2 nm 1033.6 nm, and between 1068.35 nm to 1068.75 nm NIST is seeking information from sources that may be capable of providing a solution that will achieve the

objectives described above, in addition to the following essential

requirements Contract Line-Item Number (CLIN) 0001: The Contractor shall provide one (1) 1033 nm laser and one (1) 1068 nm laser The system shall meet or exceed the technical specifications identified below. All items must be new. Used or remanufactured equipment will not be considered for award. Experimental, prototype, or custom items will not be considered. The use of “gray market” components not authorized for sale in the U.S. by the Contractor is not acceptable.
