提高腔靶激光能量注入率的新途径

  • 摘要: 在“星光Ⅱ”上测量了入射孔边缘镀CH膜的孔靶激光能量注入率,给出了注入率随入射激光能量和波长变化的经验公式,同时对堵口现象物理机理进行了一维数值模拟。实验结果表明:镀CH膜是增加激光能量注入率、提高腔靶辐射温度的有效方法。

     

    Abstract: Laser energyinjection efficiencywas measured at “Xinguang Ⅱ” under the conditions where CHfoils were plated onthe edge of laser entrance hole. The physics mechanism of enclosure was displayed by onedimensional numericalsimulation. The experimental results show that CHplating hole targets havehigher laser energy injection efficiency.
