摘　　要：介绍了激光打靶产生短脉冲强Ｘ光辐射的方法，给出了打钠靶的数值模拟结果。数值研究短脉冲强钠Ｘ光泵浦氖激光介质的Ｘ光激光，通过在氖中加氢的办法降低了电子温度，有效地提高了激光增益。研究了短脉冲强Ｘ光泵浦的高增益光电离三体复合Ｘ光激光机制，提出了在大中型激光器上开展这种Ｘ光激光研究的想法。A method for generating the short pulse intense X ray radiation in a laser produced Na plasma is described. X ray lasers that a Ne plasma is pumped by the intense Na radiation is simulated.By mixing a large amount of hydrogen with Ne,electron temperature is very low and laser gain is increased obviously.The high gain photoionization and three body recombination X ray laser scheme pumped by the short pulse intense X ray radiation is studied.
