Based on periodically poled LiNbO3 doped with MgO,the output characteristic is discussed in singly-resonant optical parametric oscillators.The influences of the cavity length,the crystal length,the pump pulse width and the transmission of output coupling on the threshold pump power are analyzed.Optical parametric oscillator is pumped by acousto-optically Q switched Nd:YVO_4 laser in the experiment.At 30℃,the threshold pump power of 48 mW is obtained with pulses repetition rate 2 kHz,the signal output power of 25mW is obtained with a pump power 94 mW,which possess the optical-optical conversion efficiency of 26.6%.
