During the last decades a phase locking phenomenon has been observed for second harmonic (SH) generation but only recently it was recognized as such in systematic studies. The general solution of the SHG from a linear/nonlinear boundary layer is composed of one reflected and two forward propagating components. We show that the conversion efficiency of the PL SH component may be substantially increased when propagation occurs in a cavity designed to be resonant for the FF. Designing cavities with higher Q-factor the SH efficiency can be improved by several orders of magnitude. This PL effect stands also for the third harmonic generation.
