摘要
研制了一台重复频率放电引发的脉冲HF(DF)激光器,采用了横向放电、横向流动和侧面滑闪预电离结构,该激光器的有效增益体积为80 cm×2.5 cm×2 cm,最大输出激光脉冲能量1.6(1.2)J,重复频率1~3 Hz,采用特种碱性分子筛吸附剂对化学反应生成物进行吸收,激光器在准封离状态下以重复频率2 Hz运转,103个脉冲后激光脉冲能量仅有20%的下降。
A periodically pulsed HF/DF gas discharge laser with an active medium volume of 80 cm × 2.5 cm×2 cm is described.A pulse repetition rate of 1~3 Hz and output energy of 1.6(1.2) J per pulse have been obtained.A alkalescent Zeolite-based absorber is used to stabilize the laser pulse energy with the forced circulation of the laser mixture.An laser energy decreased by only 20% after 103 laser shots is obtained at a pulse repetition rate of 2 Hz.
