THEORY OF DEGENERATE AND NEARLY DEGENERATE FOUR-WAVE MIXING IN PLASMAS IN THE CASE OF TRANSMISSION GRATING CONFIGURATION

本文系统研究了波波相互作用形成透射光栅情况下的等离子体简并与近简并四波混频理论,导出普适四波非线性耦合方程组,并求出其精确解析解。这一理论将有助于研制各种微波频段内快速响应非线性光学元件。

In this paper, the theory of degenerate and nearly degenerate four wave mixing in plasmas in transmission geometry is investigated. The universal set of four wave nonlinear coupled equations is obtained and its exact solution is found. The theoy can be helpful in developing various high speed nonlinear optical devices in the range of microwave frequencies.
