Paper Abstract

The potentiality to increase light pulse conversion efficiency into pulses of the millimeter and submillimeter (GHz - THz) range using the waveguide partially filled with a nonlinear crystal is suggested. This technique has been theoretically substantiated and experimentally studied. Phase matching is defined by the degree of partial filling. The calculated data as well as the experimental results of the difference frequency generation in LiNbO3, ZnTe, GaAs and DAST crystals are presented. DAST refractive index as well as its tn(delta) have been measured in the 70 - 900 GHz frequency range.
