周期极化LiTaO3的准连续倍频
Quasi-cw Frequency Doubling in Bulk Periodically Poled LiTaO3
【摘要】 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 10 6 4nm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 193mW时 ,其外腔单通倍频转换效率达到 13 5 %。
【Abstract】 Using a uncoated bulk periodically poled LiTaO 3 with the period of 7.81 μm to double the frequency of a diode-pump Q-switched Nd∶YVO 4 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℃.
