【摘要】 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,通过对激光光学系统中球差与像方束腰半径之间关系的推导,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随之改变的规律。分析结果表明,激光光学系统设计时,应该根据物方束腰的位置决定是否考虑球差对像方束腰的影响。最后通过大气激光系统中光学天线的设计实例给出了球差对高斯光束像方束腰的影响。更多还原

【Abstract】 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 relation of spherical aberration and image beam waist radius in the laser optical system is deduced.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.The analysis results indicate that the effect of spherical aberration on the radius of image beam waist should be considered according to the position of objective beam waist in the design of laser optical system.Finally,a design example of optical system used for atmospheric laser communication system is given to illustrate the effect of spherical aberration on the image beam waist.更多还原
