By using short-pulse field,the periodically poled grating(Λ=29μm) was successfully fabricated in 1.0mm thick MgO:LiNbO3(mole fraction of doped MgO is 0.05).A high-repetition-rate optical parametric generation(OPG) based on PPMgLN pumped by a 1.064μm acousto-optically Q-switched Nd:YVO4 laser.Under the condition of 3W of input pump power,44mW of output signal power was obtained,and the conversion efficiency was 1.5%.Furthermore a tunable infrared(IR) output from 1.4538μm~1.4750μm was obtained by tuning the temperature of PPMgLN(45℃~160℃).
