Abstract

We present the results of recording of amplitude gratings in ${\mathrm{Sr}}_x{\mathrm{Ba}}_{1-x}{\mathrm{Nb}}_2{\mathrm{O}}_6$ (SBN) crystals. To eliminate the photorefractive effect we used nonpoled samples. A simple technique defined the susceptibility of doped SBN to amplitude gratings recording. It was shown that, of SBN crystals doped with Ce, Cr, and Co, SBN:Co is the most effective material for use in investigating the photochromic effect. This material has a strong dichroism in linear and photoinduced absorption. The steady-state and dynamic behavior of absorption gratings in nonpoled SBN:Co crystals was studied by the two-wave mixing technique. The study is important both for the optimization of doped SBN for photorefractive applications and for characterization of the electronic structure of defects in these materials.
