摘要
文章主要针对激光光学系统设计中存在的球差对高斯光束像方束腰半径的影响进行了详细的讨论,并给出了具体关系。同时以曲线的形式分析了当物方束腰的位置和光学系统焦距变化时,由球差引起的像方束腰半径变化量也随之改变。最后通过激光羽烟衰减测试系统中聚光光学系统的设计实例说明了球差对高斯光束像方束腰的影响。
The effect of spherical aberration on the radius of image beam waist in the design of laser optical system is discussed in detail, and the expression is presented. Radius variation of image beam waist due to spherical aberration which varies with the position of objective beam waist and optical system focus is analysed by the form of curve. Finally, a design example of optical system used for smog attenuation testing system is given to illustrate the effect of spherical aberration on the image beam waist.
