High repetition rate optical parametric oscillator based on a periodically poled lithium niobate crystal pumped by nanosecond Qswitched Nd:YVO4 laser
We report the optimization of a tunable source of near-infrared radiation based on a multigrating periodically poled lithium niobate (PPLN). The pump source for the PPLN optical parametric oscillator (OPO) was diode pumped Qswitched nanosecond Nd:YVO4 laser emitting the radiation at 1064 nm with the pulse repetition rate from 0.2 kHz to 40 kHz. The influence of the output-coupler and the resonator length on the efficiency of the PPLN OPO was investigated. For this aim eight mirrors with different reflectance were tested. A minimum threshold of 30 μJ was measured. The highest output power was 660 mW at 1.64 μm when the pump power was 3 W at 15 kHz pulse repetition rate. The bulk grating periods of the PPLN structure determined the signal in the range of 1.49-2.1 μm and idler in the range of 2.1-3.8 μm.
