Abstract: Ionization rate of Hydrogen atom in a two-color laser field is calculated by using the method developed by Kulander etc.Change of ionization rate-phase relation is found when the field intensity goes up to threshold and comparison with classical calculation has been done.

Key words: two-color ionization, tunneling ionization, over-barrier ionization, threshold field intensity
