Nonlinear phase change in type II second-harmonic generation under exact phase-matched conditions.
The process of type II second-harmonic generation has been investigated theoretically. It is found that, unlike in the process of type I second-harmonic generation, phase matching is not necessary for a significant shift of the pump wave phase to be produced. The simple inequality of the intensities of interacting waves suffices for this effect to occur.
