Including non-zero initial momenta for ejected electrons in strong infrared laser fields is further developed [compare Ristic et al. 2007]. It has been stressed that, apart from being natural, the including non-zero initial momenta enables one to go into deeper analysis of the process of tunnel ionization of atoms in strong laser fields (intensity up to 10^16 W/cm^2). It is indicated that all electrons that could be ejected, under the circumstances, are ejected at field intensity sim 10^13 W/cm^2, and that the effect of ionization after that is strongly diminished, which can be seen from the slope of the plates on Fig. 2. This, also, explains the saturation effect for the fields up to 10^16 W/cm^2 (Ristic et al. 2006, Ristic and Stefanovic 2007, Ristic et al. 1998, Milosevic et al. 2002), and probably this saturation goes on until the fields raising relativistic effects sim 10^18 W/cm^2 (Milosevic et al. 2002). Opposite to what was believed earlier (Milosevic et al. 2002), that atomic field intensities could be raised to values over 10^17 W/cm^2 only when more than 10 electrons are ejected from the atom, it is shown that, properly calculated, ionization of 9 electrons raises the atomic field intensity to sim 10^18 W/cm^2.
