| 摘 要： | 脉冲染料激光器的可见光波段辐射通过共线倍频和非共线混频实现紫外波段的连续可调谐输出.本文报道了一种闭环跟踪方法;在调谐起始波长处,将取样光束在垂直相位匹配方向分割成等光强的两部分,然后在波长调谐时比较和平衡这两部分光强.对该方法在理论上作了分析并在实验中得到成功的验证.获得的自动跟踪效率大于90%.

| Abstract: | Continuously tunable UV radiation is obtained by oollinear doubling and non-collinear mixing from visible radiation of pulsed dye laser. A closed loop method, in which a sample light spot is separated into two equipower parts in the direction perpedicular to phase matching at beginning wavelength of tuning range, then the powers of two parts are compared and balanced in the tuning is reported. This method is analyzed theoretically and demonstrated successfully in our experiment. The auto-tracling efficiency is better than 90%. |
