本文研究了氖、氩、氙在高强度钛宝石激光场中的多重电离。得到了前六个电荷的氙离子产额与激光强度的关系曲线。电荷2+~ 6+曲线呈现明显的结构，这可能是由于非顺序电离过程的发生。此外，Ar的前三个电荷的离子产率与先前获得的结果内不同的激光场（钕玻璃激光器，）的比较表明，非顺序电离是强烈的波长依赖性。
Multiple ionization of neon, argon and xenon in a high-intensity Ti:Sapphire laser field has been studied. Ion yield curves of xenon versus laser intensity have been obtained for the first six charges. Curves of charges 2+ to 6+ present obvious structures which can be attributed to the occurrence of non-sequential ionization processes. Also, comparison of the ion yields of the first three charges of Ar with previously obtained results inside a different laser field (Nd:Glass laser , ) indicates that non-sequential ionization is strongly wavelength dependent.
