Abstract:We demonstrated the phase-locking and continuous tuning capabilities of a continuous-wave, monolithic optical parametric oscillator (cw-OPO). At first, the cw-OPO was phase-locked to an optical frequency comb in the 830 nm region. The residual phase noise under phase-locking was 220 mrad in rms and the energy concentration to the carrier was 95 %. Next, the signal light from the cw-OPO was phase-modulated by an extemal electrooptic modulator (EOM) in the microwave frequency. The single sideband was extracted b… Show more
