Abstract:
In this paper, we experimentally demonstrate the generation of the second harmonic radiation of the gyrotron with an operating frequency of 263 GHz due to the second order lattice nonlinearity in indium phosphide crystals doped with ferrum. It is shown that the second harmonic radiation can be used for magnetospectroscopy of semiconductor nanostructures. We discuss the possibility of generating a difference frequency in these crystals when excited by two sources of the mid-IR range with a close wavelength.
Keywords:
nonlinear frequency transformations, terahertz radiation, indium phosphide, second order nonlinearity.
