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

Summary form only given. We have investigated the intense THz radiation from InAs by applying a strong magnetic field up to 5T. The sample was non-doped bulk InAs with a [100] surface. A mode-locked Ti:sapphire laser was used for an excitation source. A liquid-helium-cooled Si bolometer was provided for detection. We show magnetic field dependence of the THz-radiation intensity. To obtain more detailed information, we took spectra by a polarizing Michelson interferometer. We show the center frequency at each magnetic field.
