Narrow-pulse Q-switched Tunable Cr:LiSAF Laser and Its Application
摘要
研究了窄脉冲宽调谐调Q Cr:LiSAF激光器的输出特性，在峰值波长850 nm附近获得了单脉冲能量为214 mJ，脉宽为20 ns的稳定调Q输出,线宽小于0.2 nm。分析了Cr:LiSAF激光器中影响调Q的因素和晶体损伤问题，研究了基于Cr:LiSAF的双波长可调谐激光器在差分吸收激光雷达中的应用。
Abstract
A narrow-pulse Q-switched tunable Cr:LiSAF laser is reported in this paper. Stable Q-switched output was obtained at 850 nm with energy of 214 mJ per pulse and pulse-width of 20 ns (FWHM) and linewidth less then 0.2 nm. The factors inducing damage of the Cr:LiSAF crystal were discussed, and a dual-wavelength tunable laser based on Cr:LiSAF is studied which can be used in DIAL (differential absorption lidar ) system.
