Abstract
A continuous-wave (cw) optical frequency synthesizer is demonstrated by using a monolithic-type cw optical parametric oscillator (cw-OPO) and an optical frequency comb. The cw-OPO is phase locked to an optical frequency comb that is phase locked to an atomic clock. The output frequency of the cw-OPO is frequency shifted with an electro-optic modulator, which makes it possible to tune the frequency continuously over . Furthermore, Doppler-free spectroscopy is performed using the optical frequency synthesizer for a cesium D1 line at . The observed linewidth of is the natural linewidth of cesium. The center frequency of the line is consistent with a previous report.
