三波混频的混沌特性

Properties of Chaose in three-wave Mixing

从三波混频的稳态方程出发，由状态密度矩阵表示，在相位匹配条件下，导出了与单模激光场相类似的光场方程。由哈肯的单模光场理论可知，单模光场具有洛伦兹型混沌，从而可知三波混频也具有洛伦兹型混沌。

Under the phase-matched condition,a light field equation,based on the three-wave mixing equation and expressed by elements of adensity matrix,is found out.The equation is similar to the single model laser field.From Haken's single model light field,we know that it is a field with Lorenz-type chaose.So Three-wave mixing also has Lorenz-Type Chaose.
