Saturation of THz-radiation power from femtosecond-laser-irradiated InAs in a high magnetic field

Abstract

THz-radiation power from femtosecond-pulse-irradiated InAs is found to be saturated at the magnetic field around 3 T. Additionally, we find that this saturation magnetic field strongly depends on geometrical layout. Interesting magnetic-field dependence of the center frequency for THz radiation is also observed.
