| Bibliography: | SUN Bao-fa, GAO Ai-hua( Laboratory for Thin Film Techniques and Optical Test; School of oploelectronies Engineering, Xi' an Technological University; Xi' an 710021 , China) beam waist parameter; resonator; σ and π cireles; Gaussian beam The study on characteristics of Gauss beam has great significance for design of laser resonator with excellent performanee. This paper adopts the graphic method of σ and π circles propagation to analyze tile beam characteristics of Gauss beam in a straight resonantor. Using the geometric relation between the parameters, the research question can be divided into the ipsilateral and contralateral two questions, by the related calculation formula, the waist parameter b is obtained. Finally using the Matlab software the cavity mirror when two are completely identical is calculated and the parameters of the Gaussian beam are obtained. The calculation results show that this method is simple and feasible, is consistent with actual situation, and has a certain practical value. 31-1707/T  |
