Abstract

The periodic `autowave' photoinduced light scattering process during steady-state optical excitation of the photorefractive ferroelectric crystal LiNbO₃ has been investigated. Autowave instability was considered for the crystals with cubic nonlinearity within the framework of the four-wave interactions. The transverse instability of the interacting fields was taken into account. The conditions for existence of such phenomenon were found. The influence of the photovoltaic effect and charge carriers diffusion on frequency spectrum of autowaves generation was studied.
