利用高压脉冲周期极化的LiTaO3(PPLT)，对半导体激光抽运Nd∶YVO4晶体1064 nm准连续输出进行倍频，讨论了其倍频转换效率及倍频过程中的温度调谐特性，实验结果与理论吻合很好。在基频光输出为193 mW时，其外腔单通倍频转换效率达到13.5%。

Using a uncoated bulk periodically poled LiTaO3 with the period of 7.81 μm to double the frequency of a diode-pump Q-switched Nd∶YVO4 laser is studied. The laser is with a 60 ns pulse duration, 10 kHz repetition rate. Internal conversion efficiency is 13.5% when pump power is 193 mW. The second-harmonic power as the function of crystal temperature is also measured, which is agreement very well with the theory. The phase matching temperature is 36.1℃.
