Optical Frequency Combs

The National Institute of Standards and Technology (NIST) is seeking to purchase optical frequency comb systems for optical clocks. The systems must have a repetition rate of 200 MHz or greater, turnkey operation, and high-speed modulation of f_rep and f_CEO. The systems must also have built-in stabilization of f_CEO, phase noise < 1 radian integrated 10 Hz to 1 MHz, and <5e-17 frequency instability at 1 second, in-loop. The systems must be capable of operating continuously for multiple consecutive weeks. • The systems must have modules for optical heterodyne beats and laser locking at specific wavelengths. • The systems must have locking electronics for f_CEO, f_rep, and external lasers at specific wavelengths. • The systems must have a total package size for comb, wavelength extension modules, and electronics that is <= 8U rack-mountable package. • On-site installation and training are required.
