Abstract
In this paper, the feature of the propagation and transformation of Gaussian beam through an optical system is analysed detailedly on the bassis of the ABCD law of Gaussian beam in terms of Gaussian Brackets. Then, a variety of typically optical systems or some special eases are discussed deeply. Finally, some important conclusions, which are practically applied, are obtained.
