模拟ps激光驱动的类氖锗19.6nm X光激光
Simulation of Ne-like Ge 19.6 nm X-ray laser driven by picosecond laser pulse
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 collisionalexcitation(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 at1.053 μm aresimulated. The local gain greater than 60 cm-1 is predicted and calculations of thepropagation of X-ray laser, including refraction effects, are done to understand whichregions have the right combination of high gain and low density gradients for an optimumcontribution to the X-ray laser output.
