摘要: 基于广义惠更斯-菲涅耳衍射积分公式,在较为普遍情况下,对高斯光束通过球差透镜的聚焦特性作了研究,给出了数值计算例.分析表明,当入射光束束腰宽度较小时,结果与文献[1]和文献[2]的有关结论相符.

Abstract: Based on the general Huygens-Fresnel diffraction integral formula,the focusing property of Gaussian beams through a spherical aberrant lens is studied.Numerical illustrative examples are given.It is shown that if the waist width of the incident Gaussian beams is relatively small,our results reduce to those of references[1] and [2].
