摘要
本文采用传递矩阵法研究了高斯光束在一种逆抛物型梯度折射率纤维中的传播规律,得出光斑半径、波面曲率半径与矩阵元之间的关系式。基于此,讨论了这种逆抛物型梯度折射率激光准直元件的原理。
Using the transfer matrix,we have studied the transmis- sion characteristics of Gaussian beam propagating through a reversal parabolic GRIN rod,such as beam spot radius,the relation between the curvature radius of wavefront and the matrix elements.Bases on the stady,we also consider the reversal parabolic GRIN rod can be used as a laser collimation element.
