Abstract
We present an optical frequency comb generator (OFCG) based on a fiber ring laser that provides a bandwidth of over 700 GHz with modeless operation. The OFCG was developed via a configuration with frequency shifted feedback fiber ring laser utilizing an acousto-optic modulator (AOM) with a carrier frequency of 150 MHz when acetylene stabilized laser was injected into the fiber ring cavity as a seeding laser. The comb frequency stability of OFCG was estimated to be 3.3 times 10-10 for a Is averaging time. The OFCG was used to evaluate the frequency measurement of test laser (unstabilized laser).
