Abstract: Terahertz band (wavelengths from 1 mm up to 30 mm) remains little-studied up to the last-time, this is connected with the lack of a powerful source of radiation, and receivers. The work considers the conversion of coherent infrared radiation -laser to radiation with length of about 100 microns (3 THz) with the nonlinear planar dielectric crystal  waveguide. The matching wave equation is solved. Characteristics of the conversion are found.

Key words: Terahertz band, nonlinearity, frequency conversion, dielectric waveguide, matching wave equation, phase matching, energy-conversion efficiency.
