M. Belic et M. Petrovic, UNIFIED METHOD FOR SOLUTION OF WAVE-EQUATIONS IN PHOTOREFRACTIVE MEDIA, Journal of the Optical Society of America. B, Optical physics, 11(3), 1994, pp. 481-485
A unified but simple method for solution of four-wave mixing equations
in photorefractive crystals in both transmission and reflection geome
tries is presented. The method is applied to the problems of double ph
ase conjugation and two-wave mixing with crossed polarizations in cubi
c crystals.
