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

Summary form only given. We report saturation of THz-radiation from femtosecond-laser irradiated InAs in a high magnetic field We have found the saturation of the THz-radiation power on the applied magnetic field. The optimum magnetic field was found to be 3 T. We have also observed interesting dependence of the frequency and the spectral width of the radiation.
