Abstract

Photorefractive gratings are recorded by two coherent red beams in lithium niobate with surface doping by iron and copper. An influence of short-wavelength incoherent irradiation on optical absorption and characteristics of a grating erasure in conditions of its readout by one of recording beams is experimentally investigated.
