Mode Conversion of a Gaussian Beam through a Nonlinear Focusing GRIN Optical Fiber

导出了非线性聚焦梯度折射率光纤中高斯光束模式变换的新公式。数值结果表明，足够大的入射光束的功率对模式变换有显著影响。

New formulas of mode conversion for a Gaussian beam through a nonlinear focusing graded-index(GRIN) optical fiber are derived.The numerical results show that the power of the incedent Gaussian beam has great effect on the mode conversion when it is large enough.
