Abstract

By using phase average method, the ionization dynamics of the hydrogen ground state (1s) under an intense high-frequency laser pulse has been studied in details. The influence of the laser frequency, polarization, pulse length and phase upon the ionization rate are explored. It is found that the ionization is very sensitive to the pulse phase. According to the steepness of the pulse rising and falling time, we found a “mixed regime” in the pulse phase, which can be used to explain the different dynamics of the ionization.

Key words： high-frequency intense laser field; hydrogen ionization; atomic stabilization; photon-electron angular distribution
