利用一维拉格朗日流体动力学模拟程序对由纳秒预脉冲和皮秒主脉冲相结合而成的抽运脉冲组合 ,产生瞬态类氖铁x射线激光 (2 5 5nm ,3p→ 3s,J=0→ 1 )的过程进行了优化计算 .通过对抽运脉冲组合的强度、宽度、脉冲间隔等参数的优化计算 ,得到了在预脉冲将靶物质充分电离到类氖离化态的前提下 (类氖离子丰度 >80 %) ,在主预脉冲峰值之间的脉冲间隔为零时 ,产生有效增益的条件是最好的 .这一结论与实验结果相符
Using a one-dimensional Lagrangian hydrodynamic simulation program, a combination of pumping pulses consisting of a nanosecond pre-pulse and a picosecond main pulse produces a transient neon-x-ray laser (25.5nm, 3p → 3s , J = 0 → 1) through optimization calculation of parameters such as intensity, width and pulse interval of the pumping pulse combination, we obtain that when the pre-pulse fully ionizes the target material to the neon-like ionized state On the premise that the neon ion abundance is> 80%, the effective gain is the best when the pulse interval between the main pre-pulse peaks is zero. This conclusion is consistent with the experimental results
