The basic principles of designing the variable reflectivity mirrors with a super Gaussianprofile are introduced.
本文介绍了超高斯渐变反射率激光反射镜设计的基本原理。

Conditions by which a circular symmetrical focussed spot can be obtained when the incident laser beam is an elliptical Gaussianprofile are determined.
确定了当入射光场为椭圆高斯分布时，获得圆对称聚焦光斑的条件。

Compared with that with uniform period, the reflectivity of Gaussianprofile grating with nonuniform period has almost no resonance side lobes at shorter wavelength.
