Intensity dependent change of the polarization state as a result of non-linear phase shift in type II frequency doubling crystals
Abstract
The effect of an intensity dependent change of the polarization state of the fundamental wave involved in imbalanced type II frequency doubling is considered. The effect is described and derived by us as analytical formulae expressed in terms of elementary functions. We show (i) that a type II second harmonic generation crystal can be considered as a wave plate with intensity dependent retardation and (ii) that the system "polarizer-type II frequency doubling crystal-analyser" has strong pulse shortening and self-induced transparency.
