Robust and low-SWaP Laser Sources for Optical Atomic Clocks

This proposal will develop a monolithic, robust, low size, weight and power, 1 GHz repetition rate femtosecond oscillator and frequency comb for microwave generation from optical atomic clocks. The oscillator has been tested in the laboratory, being constructed using prototype bonding methods. The results have been exceptional with low phase noise, long lock times with low bandwidth control loops, and reliable operation. The development will bond the constituent components to withstand high accelerations and temperature cycling. Integrated optics will be used for supercontinuum generation and generation of 778 nm light. The system will be controlled with an FPGA.
