Abstract
Threshold analysis for transverse instabilities in photorefractive cou nterpropagating two-wave mixing through reflection gratings is perform ed. A numerical algorithm for the treatment of wave equations in this geometry is developed, displaying the emergence of running transverse waves. They appear above a threshold in the applied electric field, an d their transverse wave number and oscillation frequency agree well wi th the values predicted by stability analysis.
