| 摘 要： | 利用平场光栅谱仪，分别在2和3 kPa的低气压下，测量了脉宽35 fs的圆偏振超强超短激光脉冲与5 mm长氙气体靶相互作用产生的波长在5～60 nm范围内的离子谱线。2 kPa时最强的跃迁为XeⅧ：4d105s(2S1/2)—4d95s5p(2P3/2)的17.085 6 nm线，3 kPa时最强的跃迁为11.343 nm的XeⅦ 4d105s2(1S0)—4d95s25f(3P1)跃迁。两种气压下，Xe均被电离到XeⅦ，XeⅧ，XeⅨ态。

| Abstract: | Using flat-field grating Spectrometer, the ions lines with wavelength between 5 and 60 nm were measured, which were produced by the interaction of circularly polarized 35 femtosecond ultraintense and ultrashort laser-pulse with 5 mm length xenon at the pressure 2 and 3 kPa respectively. The highest transition is the XeVIII: 4d10 5s(2 S1/2)--4d9 5s5p('P3/2) line at wavelength 17.0856 nm at 2 kPa and 3 kPa, the highest transition is 11.343 nm line of XeVII 4d10 5s2(1S0)--4d9 5s5f(3P1) transition. The xenon is ionized to XeVII, XeVIII and XeIX at both pressure. |
