摘要
本文研究高斯光束经抛物形梯度折射率纤维透镜的传播。其结果表明,当物距大于瑞利距离时,简化模型可描述高斯光束经这种纤维透镜的物像变换。最后讨论了这种模型的一些应用实例。
Gaussian beam propagation through a parabolic GRIN lens is studied. It is shown that a simple model can be used to describe the object-image transformation of Gaussian beams through the lens when the object distance is lenger than the Rayleigh distance. Some design applications of this model are finally discussed.
