| 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1 ps，波长1.053 μm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60 cm
-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。

| Abstract: | 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. |

| Keywords: | Transient collisional excitation Gain Refraction X-ray Laser |
