Symmetries of two-wave mixing equations in photorefractive
crystals are considered using group theoretical methods. Symmetry groups
for both the equations and conserved quantities are determined, and the
corresponding generators are written down explicitly. result obtained
for the plane-paralel polarized two-wave mixing are used to introduce
the method for solution and the form of solutions for the cross
polarized two-wave mixing
