| 摘 要： | 根据变分法和ABCD定律,导出了非线性锥形梯度折射率棒透镜中高斯光束的成像公式.结果表明,这种透镜的成像特性与光线轨迹依赖于光功率.当n_2=0(n_2:非线性系数)以及几何光学近似下,成像公式就简化为已知的结果.

| Abstract: | Imaging formulas of Gaussian beams in nonlinear conical GRIN rod lenses are derived from the variational method and the ABCD law. It is shown that the imaging properties and the ray paths of such lenses depend on the optical power. The imaging formulas reduce to the known results when n2 = 0 ( n2 :the nonlinear coefficient) and under the geometrical optics approximation. |
