Paper Abstract

The possibility of increasing the light transformation efficiency into SHF range by means of nonlinear crystal partially filling cross-section of the waveguide is suggested, theoretically grounded, and experimentally realized. The phase matching condition is provided by the degree of partial filling. Difference frequency radiation slowing factors and optimal thickness of LiNbO3 crystal are calculated for USP generation within the range of 2 - 46 mm. USP SHF train with a frequency repetition of approximately 108 Hz and transformation efficiency in energy pumping up to 28% of maximum value is obtained.
