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
Dispensing prism resonant Q-switched operation is discussed. Which prism both play the role of wavelength tuning dispersion element, but also play the role of Q switch polarizer, eliminating the need for the production of broadband polarizer. In order to make the crystal high voltage synchronously operate with the wavelength tuning, a single-chip microcomputer is used to control the total mirror drive power and the Q-adjusting voltage so that the rotation of the total reflection mirror runs synchronously with the high voltage applied to the crystal to achieve broadband tuning and Q The voltage synchronous operation of the purpose of obtaining a wavelength-tuned giant-pulse laser. In the experiment, the exact digital retarded retardation technique and the synchronous operation of crystal pressure and wavelength tuning were used to obtain the result of laser pulse width 31ns and energy 2 70mJ
