Abstract
Multiply charged ion production in rare gases (He, Ne, Ar and Xe) has been investigated using a 1-ps Nd-glass laser pulse at (lambda) equals 1053 nm with intensities in the 1013 - 1018 W/cm2 range, for both linearly and circularly polarized light. At the maximum laser intensity, all electrons of the outer shell are removed, except in Ne for which charge states up to 7+ are observed. Comparison of experimental data with Ammosov et al tunneling model shows a very good agreement for both polarizations, indicating that ionization with a 1 ps pulse in the near infrared light mainly occur in tunneling regime, while for longer pulses multiphoton processes dominate. The ion production curves obtained with linear and circular polarization light show that (1) ionization threshold intensities are at least 40% higher for circular polarized light, and (2) ionization by direct processes are never observed in circular polarized light.
