"Second-harmonic generation under conditions of simultaneous phase-matched and quasi-phase-matched interactions in nonlinear crystals with a regular domain structure"
Quantum Electronics (Rus.), 1999, v.26, N2, p.155-157
Characteristic features of simultaneous generation under conditions of phase-matched and quasi-phase-matched interactions in crystals with a regular domain structure were investigated. Under such conditions the efficiency of second-harmonic generation may prove higher than the generation in homogeneous crystals.
