| Abstract: | The influence of an intense laser field on the intraband motion of a charge carrier in the localized moment potential of a ferromagnetic semiconductor is discussed. The quasienergy spectrum of a free carrier is calculated and it is shown that for very large fields the energy-gap between the spin branches decreases with increasing laser amplitude. |
