In this paper, systemic optimum designs and theoretical analysis to Ne-like Ge XRL driven by pre-main short pulses were conducted by a series of codes, which had been tested by experiments. Simulation results show that, adopting driven conditions of 2%~3% pre-pulse , 6~8ns pre-main pulse interval and 40TW/cm~2 power intensity,a gain area of 19.6nm laser line beyond 60μm and gain duration of 90ps can be obtained. Furthermore, with 16mm plane target, the gain gets to 11.8/cm, and if 6mrad/cm curved target is adopted, it reaches to 13.3/cm, and small signal gain-length product gain-length product of single target is about 21.3, which means that saturated gain can be realized by a single target. With double targets opposite coupling, gain-length product can reach 38.4, deep saturation can be gotten, and XRL source required by demonstration of application is out of question.

In this paper, the simulation and theoretical analysis of Ni-like Ag X-ray-laser (XRL) are included, which are driven by 1.06μm pre-main-pulse with a power of 1.2×10~(13)W/cm~2. It is verified that, employing 23mm target, XRL can obtain effective amplification, which agrees with experiments. Power nonuniformity along focus line, induced by single cylindrical lens, is also considered. According to theoretical simulation, adopting curve target can effectively overcome the effect of reflection and the disadvantage of this nonuniformity. Lower limit of drive power needed by output of Ni-like Ag XRL, predicted by theoretical simulation, also agrees with experiments. Theoretical simulation shows that, using 1% pre-pulse, if appropriate optimization of time interval between pre-and main pulse has been conducted, the output energy of XRL as well as conversion efficiency of energy can be dramatically enhanced.

 在1.2×1013W·cm-2低功率密度下,对基频激光预主短脉冲驱动类镍银X光激光机理进行了数值模拟和理论分析。证实了在靶长23mm范围内X光激光都能获得有效放大,取得了和实验相符合的结果。考虑了单柱面镜线聚焦沿靶长度方向功率密度的非均匀性对X光激光放大的影响,采用弯曲靶能有效克服折射以及单柱面镜线聚焦功率密度非均匀带来的不利影响。理论模拟给出的类镍银X光激光的出光下限泵浦功率密度也与实验符合得很好。理论模拟还表明,采用1%左右的预脉冲强度并对预主脉冲时间间隔进行优化,X光激光的输出能量和能量转换效率将获得大幅度提高。
