A first order quasi phase matched periodically poled LiNbO 3 for SHG with 6.5 μm period, 12 mm length, 10 mm width and 0.5 mm thickness has been successfully fabricated by applying an external electric field at room temperature from an high pulsed voltage generator. About 18 mW of CW 0.532 μm green light was obtained pumped by an 1.1 W of CW 1.064 μm Nd∶YAG laser with end coupling, which corresponds to 1.6% power conversion efficiency.

通过高压脉冲电场极化,制备了周期为6.5 μm、长为12 mm、宽为10 mm、厚为0.5 mm的一阶准相位匹配周期性极化铌酸锂;由1.1 W连续1.06 μm Nd:YAG激光器抽运,在5°时产生了约18 mW、0.532 μm的倍频连续绿光,其对应的二次谐波转换效率约为1.6%,二次谐波的归一化转换效率约为1.5% cm-1W-1,相当于79%的周期性极化铌酸锂的理想非线性系数。
