Multistep Parametric Processes in Nonlinear Optics
Energy transfer between different modes and phase-matching relations are fundamental concepts in nonlinear optics. Unlike nonparametric nonlinear processes such as self-action and self-focusing of light in a nonlinear Kerr-like medium, parametric processes involve several waves at different frequencies and they require special relations between the wave numbers and wave group velocities to be satisfied, the so-called phase-matching conditions. Parametric coupling between waves occurs naturally...[Show more]
