We demonstrated 117-J laser output in a nanosecond regime with a diode-pumped Yb:YAG ceramic laser amplifier. The repetition rate was 0.05 Hz, and the pulse duration was around 40 ns. 5-J input energy was amplified by two cryogenically cooled Yb:YAG ceramic laser heads. Six Yb:YAG ceramic disks in each laser head were cooled by cryogenic helium gas with a temperature of 175 K. The output energy of the first and second laser heads was about 28 and 117 J.

在TACMI联盟中开发100-J DPSSL作为激光处理平台

我们用二极管泵浦的Yb：YAG陶瓷激光放大器演示了纳秒级117-J激光输出。重复率为0.05 Hz，脉冲持续时间约为40 ns。通过两个低温冷却的Yb：YAG陶瓷激光头放大了5J输入能量。每个激光头中的六个Yb：YAG陶瓷盘用温度为175 K的低温氦气冷却。第一和第二激光头的输出能量分别约为28和117J。
