"Multi-frequency laser radiation harmonics generation in the nonlinear crystals with a regular domain structures"
XVI International Conference on Coherent and Nonlinear Optics, 1998, Postdeadline, WP15

      The results of theoretical analysis of multi-frequency optical harmonics generation in the nonlinear crystals with regular domain structure for all types of interaction (approximately 4000 combinations) are presented. The different variants of quasi-phase matching for OPO with multiple frequencies are considered.
