摘　　要：提出并采用具有一定时间间隔的双束脉冲加热锗薄膜靶方法，在泵浦激光能量１００Ｊ，靶长１０ｍｍ的实验条件下，观察到波长１９．６１ｎｍ和２３．６３ｎｍ两条类氖锗３ｓ－３ｐ激光跃迁线。１９．６１ｎｍ（Ｊ＝０－１）的激光跃迁线发射强度较２３．６３ｎｍ（Ｊ＝２－１）激光线的强度大，其发散角较后者小。soft X-ray 3s-3p lasing transitions originating from J=0-1and J=2-1 inneon -like germanium plasma is observed about 100J pumped energy only for the first timeThe lasing plasma is produced by double pulse laser with,interval of 350ps heating 10mm longthin-film germanium targets.The line of 19.61nm(J=0-1)is more intense than that of 23.63nm(J=2-1),the divergence angle is lesser than the later.
