Abstract
We consider symmetries of two-wave mixing equations in photorefractive crystals, using group theoretical methods. Symmetry groups for both the equations and conserved quantities are determined, and the corresponding generators are written explicitly. Results obtained for plane-parallel polarized two-wave mixing are used to introduce the method for solution and the form of solutions for cross-polarized two-wave mixing.
