用于高功率径向偏振光的组合轴锥镜设计
Design of combined axicon for high power radial polarized light
摘要
Abstract
In order to increase the output laser power of radically polarized light , a W-axicon was improved by changing the internal cone angle.For a W-axicon with the external cone angle of 90°, the position and direction of the reflected light will not change for different internal cone angles through analysis according to geometrical optics.In order to study the thermal distortion characteristics of the axis cone mirror , temperature deformation simulation was conducted.The result shows that the overall temperature becomes smaller and the distribution is more uniform when the inner cone angle increases.As the inner cone angle becomes larger , the decrease in the optical path of the beam center increases with respect to the decrease in the optical path edge.The Fox-Li numerical iteration was used to simulate the laser mode of the resonator.It is found that the effect of temperature deformation on the laser mode is least when the inner cone angle is 100°.The study of W-axicon temperature deformation can provide reference for W-axicon design.关键词
