摘要: 应用衍射积分理论, 对激光在间接驱动聚变柱形靶腔内的传输特性进行了研究, 给出了柱形腔靶注入孔以及内壁上的光强分布, 并与几何光学方法所得结果进行比较, 得出几何光学方法的适用条件。Abstract: Usnig diffraction integral theory, the propagation properties of laser beams passing through a cylindrical hohlraum in indirect-driven laser fusion have been studied. The intensity distributions at the entrance hole and on the wall of the cylindrical hohlraum have been given. Our results have been compared with those calculated using geometric optics, thus the condition, under which geometric optics is valid, has been obtained.
