摘要：
Effects of order v/c in the description of intense high-frequency laser pulses for above-threshold-ionization (ATI) of hydrogen atoms are included in the numerical integration of the time-dependent Schrodinger equation. The magnetic field gives rise to a motion of the electron cloud along the propagation direction of the laser pulse. It is shown that this effect does not invalidate the recent findings of stabilization against photoionization, but modifies significantly the ATI spectra. The ATI spectrum becomes simpler again as the peak laser field reaches ulta-intense values.
