The review of recent experimental work on photorefractive grating recording and frequency degenerate nonlinear wave mixing in periodically poled lithium niobate is given. We report, in particular, on new results concerning photorefractive grating recording in periodically poled lithium niobate by two orthogonally polarized eigenwaves (ordinary and extraordinary), on coherent self-oscillation in semilinear cavity, on evaluation of the effective photovoltaic field in iron-doped periodically poled lithium niobate.
