Abstract

The work presents a theoretical analysis of quasi-phase-matched intracavity interaction in the constant-intensity approximation at frequencies summing with simultaneous regard for the losses and phases of interacting waves. An analytical expression for optimum correlation between interacting waves has been received. It is shown that, by the choice of optimum values of phase mismatch, pump intensity, and phase relationship, it is possible considerably to increase conversion efficiency in comparison with the noncavity case. The numerical estimation of expected conversion efficacy in conditions of an experiment is presented.
