| 摘 要： | 论述了色散棱镜谐振腔调Q运转方法。其中棱镜既起到波长调谐色散元件的作用 ,又起到Q开关起偏器的作用 ,省掉了制作难度大的宽带起偏器。为了使晶体高压随波长调谐同步运转 ,采用了单片机控制全反射镜驱动电源 ,同时也控制调Q电压 ,使全反射镜的转动与施加在晶体上的高压同步运行 ,达到了宽带调谐与调Q电压同步运转的目的 ,获得了波长调谐巨脉冲激光。实验中应用精确数字退压延迟技术和晶压与波长调谐同步运转方法 ,获得了激光脉宽 31ns、能量 2 70mJ的结果

| Abstract: | It is difficult to operate for Ti:sapphire laser Q switching because the lifetime of the laser upper level is short and the population is less. The analysis and design for Q switching operation of the prism dispersion resonator are given. The prism acts as both a dispersion element for tuning and a polarizer for Q switching. The broad band polarizer which makes hard is omitted. The techniques of accurate digit delay discharge of KD *P and the synchronized operation of the applied voltage on KD *P with tuning wave length has been utilized. The laser energy 270mJ per pulse and the pulse width 31ns are obtained. |
