【摘要】 文章介绍了激光高倍率扩束器的工作原理和设计思想,给出了主、副镜的焦距比及扩束器的准直倍率的公式,研究了口径为60毫米(￠60)的15倍扩束器非球面的设计,运用Zemax光学设计软件,通过改变焦距及非球面系数的方法,全面考虑球差、正弦差和发散角,给出实际设计数据和检测结果,加工装配后,结果是弥散圆半径为小于1丝,和设计的点列图是吻合的,满足设计要求,在傅立叶光学实验室运用中,取得了良好的实验效果.更多还原

【Abstract】 Operating theory and plan ideas of laser expander is proposed in this paper. Design ofaspherical expander, present the formulae that focus ratio of main -assistant lens and times of laserexpander,which multiplying power is 15 、aperture is 60mm(￠60),has been studied .Using changefocus and coefficient of aspherical ,Practical design datas and check result are took out afterprocessed and assembled. We obtain favourable experiment phenomena and datas as been used inlabs of Fourier optics .更多还原
