摘要
对用棱镜实现波长可调谐的金绿宝石激光器进行了理论和实验研究，分析了其在可调谐波段的增益和阈值特性，优化了腔形、输出镜透射率等参数，通过实验获得了调谐范围725-781nm、中心波长最大输出能量达1J的激光输出。用不同波长、不同重复频率的金绿宝石激光对扫描线阵CcD成像进行了干扰实验，获得了较好的干扰效果。
The Alexandrite laser tuned by a chromatic dispersion prism was theoretically and experimentally studied. The gain and threshold characteristics in the range of tunable wavdengths of the laser were analyzed,and the structure of resonator and the transmissivity of the output mirror was optimized, In the experiment, a maximum output energy of 1 J with a tunable range of 725--781 nm were obtained. The imaging interference experiment of a linear CCD scanning array is with presented the Alexandrite laser at different output wavelengths and repeat frequency. The results showed that laser in this spectrum range could be applied to anti-guidance weapons and anti-reconnaissance with prospect.
