摘要
基于无像差自聚焦理论 ,使用ABCD定律导出了高斯光束在非线性梯度折射率介质中的解析传输公式。采用矩阵光学方法研究了高斯光束通过非线性梯度折射率透镜的传输特性。结果表明 ,介质的非线性性和非均匀性、激光功率及入射光束参数影响其传输特性。
Based on the aberrationless theory of self-focusing,the closed-form propagation expressions for Gaussian beams through a nonlinear gradient-index medium are derived by means of the ABCD law.By using the matrix optics method,the propagation properties of Gaussian beams through a nonlinear gradient-index lens are studied.It is shown that the nonlinearity and inhomogeneity of the medium,laser power and input beam parameter affect their propagation properties.
