Abstract

Tuning and output characteristics of widely-tunable, continuous-wave, doubly-resonant optical parametric oscillators (cw-DROs) are reported from a practical viewpoint. Using 5% MgO-doped LiNbO₃ as a nonlinear crystal, we fabricated a 532 nm pumped, monolithic cw-DRO which is tunable over 1 octave from 777 nm to 1687 nm. The threshold of the DRO was 10 mW and the DRO produced the signal power of 4 mW and the idler power of 3 mW when it is pumped at 68 mW pump-power. It operated very stably in a single-longitudinal-mode pair of signal and idler without any mode-hopping over 1 day even under free-running condition, owing to the high mechanical stability of the monolithic cavity and the strong thermal self-locking mechanism. By stabilizing the crystal temperature so as to maintain the output power constant, the output power fluctuation was suppressed to 1.3% rms. The arbitrary longitudinal-mode-selection was possible by combining the crystal temperature and the pump-frequency tuning. By the simultaneous control of the crystal temperature and the pump- frequency, the continuous frequency tuning over 500 MHz was achieved.
