4 as a nonlinear crystal and obtained a pump threshold of 7 mW and an output power of 6 mW for a pump power of 40 mW. The OPO operated in a single longitudinal mode pair of a signal and an idler, over 1 h without mode hopping in the free-running condition. The signal and the idler wavelengths were tunable by 1 nm by changing the crystal temperature by 20 °C. The continuous tuning of the beat frequency between the signal and the idler was achieved by temperature tuning (slow control, 80 MHz/K) and E-field tuning (fast control, 0.75 MHz/V). We demonstrated the feasibility of frequency control by phase locking the beat frequency. The beat frequency could be successfully phase locked to a signal generated by a synthesizer through the electrooptic effect of the crystal. The phase locking could be maintained over 1 h.
