EXACT SOLUTION OF THE FOUR-WAVE MIXING IN PLASMA——THE TRANSMISSION GRATING CONFIGURATION

In this paper, the universal set of degenerate and nearly degenerate four-wave mixing nonlinear coupling equations in plasma is presented in the transmission grating configuration and its exact solution appropriate for arbitrary nonlinear complex coupling parameters is given. This solution is not only suitable for photorafractive materials it can also be helpful for further theoretical study of FWM's phase conju-gation and development of new model nonlinear optical devices.
