Generation of low-frequency radiation under the effect of an ultrashort laser pulse on a semiconductor in a magnetic field.

One of the scenarios for the generation of THz radiation under the effect of a femtosecond laser pulse on a semiconductor in a magnetic field is proposed and studied in detail. It is shown how spectral composition, shape of the pulse, and total energy of the THz pulse change as the magnetic field increases. Explicit dependencies of the THz radiation features on the parameters of the laser pulse and the semiconductor are determined.
