摘要
由正六边形的球面透镜列阵和一个非球面的主聚焦透镜组成的聚焦系统,用于改善高功率激光(10^(12)W)聚焦照明靶面的均匀性,得到实验上的证明.文中报道了采用这个聚焦系统进行的激光驱动高压冲击波实验,显示出了均匀照明对改善激光冲击波平面性的良好的效果.
The effect of a focusing system which is composed of a spherical regular hexagon lens array and an aspherieal principal focusing lens used for improving the illumination uniformity of the high power laser on the target surface has been demonstrated experimentally. We report here a excellent result that the flatness of the laser driven shock wave was improved obviously when this focusing system was used at laser beam power of 1012 W.
