在采用二级聚光的太阳能激光器聚光系统中,使用焦距为1200mm菲涅耳透镜实现一级聚光、全反射复合抛物面聚光器(CPC)实现二次聚光,对直径为6mm的工作物质进行端面泵浦。为了分析CPC各参数对聚光效率的影响,通过改变出射口半径、最大接收角,CPC位置和上下端截取比,采用Tracepro光学软件模拟系统的聚光性能。结果表明:优化后的CPC,总的聚光效率可以达到50.4%。 In the second-class condenser solar laser condenser system, the use of focal length 1200mm Fresnel lens to achieve a condenser, total reflection composite parabolic concentrator (CPC) to achieve secondary condenser, the diameter of 6mm work Material is end-pumped. In order to analyze the influence of various CPC parameters on the condensing efficiency, the optical performance of the system was simulated by using Tracepro optical software by changing the exit radius, the maximum acceptance angle, the CPC position and the upper and lower end interception ratio. The results show that the optimized CPC can achieve a total concentrating efficiency of 50.4%.
