Abstract:

Numerical calculations have shown that the phase synchronism can be realized both for H10 ground mode and higher types of Hn0 modes of the waveguide in range 44 GHz - 9.615 THz. It is shown that it is possible to control for the efficiency of transformation of waves of Hn0 type as well as spectral composition and time behavior of the THz pulse through variation of the nonlinear crystal thickness and its position relative to the narrow side of the waveguide.

Keywords:
