Paper Abstract

A slant grating was recorded with two laser beams incident on photorefractive crystal asymmetrically. 2D perturbative analysis for the first two higher-order harmonics of the space-charge field for steady-state photorefractive slant grating recording has been presented. Considering the contribution from the next-order harmonic at arbitrary modulation depths. Numerical results for the first two harmonics show that the next-order correction to the space- charge field is strongly dependent on the modulation depths. The dependence of the harmonics on spatial frequency, modulation depth and grating slant angles is discussed.
