Abstract :
Summary form only given. Our studies of light-induced scattering in periodically poled lithium niobate (PPLN:Y:Fe) have shown a wealth of qualitatively new parametric four-wave processes that involve essentially the periodicity of the domain structure. Some of them are related to charge redistribution via the spatially-oscillating photovoltaic currents. The observation of these parametric processes is a direct proof that PPLN is a new nonlinear medium appropriate for polarization sensitive grating recording.
