Abstract
A Dual frequency comb interferometer was constructed to monitor cw laser chirp rates exceeding 1500 THz/s with MHz level resolution and accuracy over a 3 THz spectral sweep. Monitoring of the chirped laser is continuous. Additionally, absolute frequency calibration, modulo 3 THz, is acquired automatically when the laser chirp rate drops below 150 GHz/s for longer than 300 υs.Citation
