超短脉冲激光频率转换材料
materials for ultrashort pulses laser frequency conversion
超短脉冲激光频率转换材料materials forultrashort Pulses laser frequeney eonversion用于脉冲宽度从微微秒直到几十毫微微秒激光的频率转换材料。超短脉冲激光具有短的脉宽，较好的模式特性以及高的峰值功率，从而具有很强的非线性性能。经频率转换后，短波的超短脉冲可产生强的光化学反应，是探索微观世界和超高速现象的极为有用的光源。此外，采用薄片倍频材料的超短脉冲倍频，可以作为超短脉冲脉宽测量的一种简便有效的方法，在技术上有实用价值。 对超短脉冲激光频率转换材料的性能主要有以下要求:①高的光损伤闭值。由于超短脉冲的高峰值功率，因而对材料的光损伤阑值提出高的要求，一般要大于GW/cmZ。②相位匹配特性。超短脉冲在空间的尺度短到毫米及几百微米量级，短脉冲波包在材料中以群速度传播。因而，除一般的相速度匹配外，还应满足群速度匹配才能获得较高的能量转换效率。对光学均匀材料，要求基频和倍频波的折射率色散小，才能获得较好的群速度匹配。对I类匹配，群速度要求稍低;对n类匹配要求太苛刻，很难应用。由于群速度失配存在，一般器件只取亚毫米的厚度。过长的光程于能量转换无补，反而引入脉宽的展宽以及能量的损耗。③透过波段。首先要求对参与频率转换的激光波长有高的透过率。对超短脉冲应用场合，材料应有更短的紫外吸收边。其原因是吸收边会增加材料的折射率色散;远离使用波长的吸收边，可使材料获得较好的群速度匹配。 钱激光超短脉冲频率转换的常用材料是磷酸二氢钾(KDP)类晶体。此外，新开发的三硼酸锉(LBO)晶体，由于其高的抗光损伤阑值、好的紫外透过率以及小的色散，也是好的超短脉冲频率转换用材料。有机晶体精氨酸磷酸盐(LAP)和氛化精氨酸磷酸盐(D一LAP)也可用作超短脉冲频率转换用材料。 (邵宗书)
