A COMPACT DEVICE BASED ON THE SOURCE OF DOUBLE COMBES USING OPTICAL MICRO RESONATORS AND A METHOD FOR HETERODYN DETECTION IN METROLOGICAL APPLICATIONS

摘要

A light source device capable of generating two different optical frequency combs with a simple structure is disclosed. The disclosed light source device includes an optical resonator and a continuous wave laser that emits a laser beam having a spectral component corresponding to the resonant frequency of the optical resonator. The optical resonator is configured to interact with the laser beam emitted from the continuous wave laser to generate a first frequency comb and a second frequency comb having different modes.
