Features of an Optical Transmission in Lithium Niobate Samples with Photorefractive Surface Doping

We observe the significant change in the optical transmittance of lithium niobate samples with surface doping by combinations of photorefractive impurities (Fe+Cu) under influence of light with wavelengths of 633 nm and 470 nm. The relative contribution of light-induced change of optical absorption...

Description
Summary:We observe the significant change in the optical transmittance of lithium niobate samples with surface doping by combinations of photorefractive impurities (Fe+Cu) under influence of light with wavelengths of 633 nm and 470 nm. The relative contribution of light-induced change of optical absorption and temperature change to this effect is experimentally investigated and discussed
