Abstract: | A relativistic semi-classical theory (RSCT) of H-atom ionization in ultra-intense laser (UIL) is proposed. A relativistic
analytical expression for ionization probability of H-atom in its ground state is given. This expression, compared with non-relativistic
expression, clearly shows the effects of the magnet vector in the laser, the non-dipole approximation and the relativistic
mass-energy relation on the ionization processes. At the same time, we show that under some conditions the relativistic expression
reduces to the non-relativistic expression of non-dipole approximation. At last, some possible applications of the relativistic
theory are briefly stated. |
