摘要
研究了窄脉冲宽调谐调 QCr:Li SAF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 2 1 4 m J,脉宽为 2 0 ns的稳定调 Q输出 ,线宽小于 0 .2 nm。分析了 Cr:Li SAF激光器中影响调 Q的因素和晶体损伤问题 ,研究了基于 Cr:Li
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.
