非线性梯度折射率棒透镜高斯光束的色差

The Chromatic Aberration of Gaussian Beams with a Nonlinear Graded Index Rod Lens

本文首次研究了高斯光束通过非线性梯度拆射率棒透镜的色差特性。导出了色差公式。结果表明，色差特性强烈依赖入射高斯光束的正规化光束功率和束腰。这在线性情形以及几何光学近似中没有相似的性质。

The characteristics of the chromatic aberration of Gaussian beams through a nonlinear graded index rod lens are studied for the first time to our knowledge. Such formulas of the chromatic aberration are derived. It is shown that the characteristics of the chromatic aberration are strongly dependent on the normalized beam power and the incident beam waist, which has no counterpart in the linear case and under the geometric optics approximation.
