摘要
以Nd:MgO:LiNbO_3同时兼作激活介质和非线性光学材料,研究自倍频激光器。用小型氙灯泵浦,在室温下获得二次谐波激光(0.547μm) 阈值小于4.8'J,最大输出400μJ/shot,工作温度范围大于20℃～45℃,无光损伤。
Self-freqency doubled laser was demonstrated by using Nd: MgO:LiNbO3 as active and nonlinaar optical medium. Pumped by a small Xe flash-lamp, the second harmonic wave (547 nm) was generatad at room-temperature with 4.8J threshold and 400μJ/shot maximum output. The tamparature range of operation is over 20℃～45℃ and photorefractive damage has not yet observed.
