Research of photorefractive properties in lithium niobate crystals by raman and photoinduced light scatering
In Raman spectra of LiNbO3 crystals with photorefractive response in Y(ZX)Y scattering geometry a significant widening was detected of the band with frequency 630 cm-1 4A1(TO) that corresponds to totally symmetrical vibrations of oxygen octahedra. Any analogous line widening was not observed in Y(ZZ...
