In many laser applications it is important to analyze the effect of the aberrations of optical systems which are employed to focus off-axis beams that only partially fill the system aperture. In this paper analytical expressions that give the position of the diffraction focus, peak intensity, and tolerance conditions for uniform and Gaussian beams in an optical system with primary spherical aberration are obtained on the basis of diffraction theory. The results presented are very useful for designing focusing systems for use with laser beams.
在许多激光应用中，分析光学系统像差的影响很重要，这些光学系统用于聚焦仅部分填充系统孔径的离轴光束。本文基于衍射理论，得出了在具有初级球差的光学系统中，给出均匀光束和高斯光束的衍射焦点位置、峰值强度以及公差条件的解析表达式。所呈现的结果对于设计用于激光束的聚焦系统非常有用。
