高功率激光多程放大系统光束传输的计算分析
-
摘要: 报道了高功率激光多程放大系统光束传输的模拟程序, 该程序考虑了放大介质的增益分布、增益饱和、增益恢复系数、介质吸收损耗、B积分以及光阑和空间滤波器等光学元件对激光传输和放大的影响, 并给出了典型的计算实例。Abstract: The simulation code for laser beams passing through a multipass amplifer system has been psented, where the gain distribution, gain saturation, gain recovery parameter, absorption loss, Bintegral and optical elements, such as aperture and spatial filter, which influence laser beam propagation and amplification have been all considered. Numerical illustrative examples have been given ．
