Abstract
The effect of second harmonic generation of idler wave on the process of difference frequency generation is analyzed theoretically. It is shown that, in general, the presence of second harmonic generation has a favorable influence on the evolution of the difference frequency wave. When the two processes are exactly phase matched, the usual oscillations in the variation of generated wave intensity with the interaction length are almost completely eliminated while retaining nearly complete conversion.
