非线性锥形梯度折射率透镜的光学特征

Optical Characteristics of Nonlinear Conical GRIN Lenses

本文对非线性锥形梯度折射率透镜进行了分析,根据稳态自聚焦理论以及ABCD定律,导出了高斯光束通过这种透镜光斑尺寸及其位置的公式。讨论了几种特殊的情况,得到了一些重要的结果。

In this paper, the nonlinear conical GRIN lenses are analysed. Formulas forthe spot size and its position of Gaussian beams of light through such lenses arederived from the steady--state self--focusing theory and ABCD law. Severalspecial cases are discussed and some important results are obtained.
