摘　　要：利用外加电场的方式 ,在 0 .5 mm厚的 z切铌酸锂晶体中实现了周期性极化反转。基频光波波长为1.0 6 4μm,功率为 1.75 W,在 2 0℃的室温下 ,得到波长为 0 .5 32μm、输出功率为 0 .9m W的连续倍频绿光输出 ,倍频转换效率为 0 .0 5 2 %。Quasi-Phase-Matched (QPM) Second Harmonic Generation (SHG) in an external field induced periodically poled lithium niobate (PPLN) was presented in this work. Samples with a 6.8 μm domain period were a mm long and 0.5 mm thick were obtained with this process for cw 1.064 μm Nd:YVO4 SHG. The output power was 0.9 mW and a normalized conversion efficiency of 0.052% to the SHG was obtained at room temperature 20°C.
