摘要
We report a narrow pulse width optical parametric oscillator based on periodically poled MgO:LiNbO3 (PPMgLN) with a high repetition rate under quasi-phase matched conditions. When the maximum pumping power of the 1,064-nm laser was 14.57 W, the acousto-optical (A-O) Q-switch repetition rate was 100 kHz, and the PPMgLN crystal grating period was 29.5 mu m. A 1,474-nm signal light output power of 4.21 W and a 3,828 nm idler light output power of 1.547 W were obtained, corresponding to a pulse width of 9.52 ns and 9.65 ns, respectively. The overall optical-optical conversion efficiency was 39.5%. Additionally, by changing the temperature from 25A degrees C to 150A degrees C, a tunable signal wavelength of 1,474-1,499 nm and idler wavelength at 3,676-3,828 nm of the output laser were achieved.
