Non-sequential multiple ionization of rare gas atoms in a Ti:Sapphire laser field
Abstract
Multiple ionization of neon, argon and xenon in a high-intensity Ti:Sapphire laser field 0953-4075/31/6/008/img1 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 0953-4075/31/6/008/img2, 0953-4075/31/6/008/img3) indicates that non-sequential ionization is strongly wavelength dependent.
