摘　　要：瞬态电子碰撞激发产生X光激光的机制可以极大减少X光激光的泵浦能量。模拟了脉宽为1ps,波长1.053μm 的钕玻璃激光驱动的类氖锗X光激光。模拟表明,在临界面附近可以产生高达60cm-1的增益,还计算了X光激光在等离子体 中的传播,计算表明X光激光在等离子体中的折射效应仍然是影响X光激光输出强度及分布的重要因素。Transient collisional excitation (TCE) has proved to be an efficient method to significantly save driving energy. In this paper, Ne-like Ge 19.6 nm X-ray laser driven by picosecond Nd:glass laser pulse at 1.053 μm are simulated. The local gain greater than 60 cm-1 is predicted and calculations of the propagation of X-ray laser, including refraction effects, are done to understand which regions have the right combination of high gain and low density gradients for an optimum contribution to the X-ray laser output.
