非线性锥型梯度折射率媒质中的模式变换

Mode conversion in a nonlinear conical graded index medium

研究非线性锥型梯度折射率媒质中的模式变换特性。导出模式变换公式，分析了光束功率、光束初始的束宽半径和波前曲率半径的倒数对模式变换的影响。

Properties of mode conversion in a nonlinear conical graded index medium are investigated.The formulas of mode conversion are derived and effects of optical beam power,initial beam width radius and inverse of the radius of curvature of the wave front on the mode conversion are analysed.
