Transformation properties of general astigmatic Gaussian beams

摘要: 强调了分析复杂像散高斯光束时应注意的一些重要问题。然后,通过数值计算以典型例说明复杂像散高斯光束与常规圆高斯光束和简单像散光束完全不同的变换特性,即:对复杂像散高斯光束,束腰不一定位于等相面曲率半径为无穷大的位置,并且,即使在自由空间中传输,也可能有几个束腰。

Abstract: In the paper,some important issues while analyzing general astigmatic Gaussian(GAG) beams are stressed on.Then typical numerical examples are given to illustrate the transformation properties of GAG beams,i.e. for GAG beams,the waist is not certainly located at the position corresponding to the infinite curvature radius of the wave-front and there may be several waists even though in free space,which are different from those of conventional stigmatic Gaussian and simple astigmatic Gaussian beams.
