Single and double tunneling ionization of the noble gases exposed to a linearly or circulary polarized laser field

摘要

We theoretically studied different influences like a nonzero initial momentumof ejected electron and the ponderomotive potential on the ionization probabilities andthe ion yields for the noble gases atoms in a linearly and circularly polarizedelectromagnetic field whose intensity varies from 1012 to 1014 Wcm-2 . The ionizationprocess occurred completely in the tunneling regime. The calculated values are inreasonable agreement with the experimental data.
