摘要：
A pulsed nanosecond optical parametric generator (OPG) in periodically poled lithium mobate (PPLN) crystal is presented. The pump laser is an acousto-optically Q-switched Nd:YVO4 laser with the maximum average power of 6.58 W. When the repetition rate is 50 kHz and the pulse width of the pump source is 80 ns, the maximum average total output power of the single-pass PPLN OPG is about 1.9 W, which includes 1.322 W of 1.536 mu m signal radiation. The length of the PPLN crystal is only 38.7mm (at room temperature) with a grating period of 28.93 mu m (at room temperature). The 1.502-1.5361 mu m signal radiation and 3.652-3.465 mu m idler radiation are obtained by adjusting the PPLN crystal temperature from 155 degrees C to 250 degrees C.
