Abstract

Effects of spherical aberrations in converging and diverging lens-axicon doublets are investigated. Intensity profiles are obtained in the line and ring focal regions by numerically solving the Fresnel-Kirchhoff integral. Comparisons with aberration-free computations show that higher peak irradiances occur for the converging doublet when spherical aberrations are included. Results are presented for axicons with small apex angles in lens-axicon combinations illuminated by collimated Gaussian 1.064-mum laser beams.

摘要

研究了会聚和发散透镜-轴棱锥双合透镜中球差的影响。通过数值求解菲涅耳-基尔霍夫积分，在直线和环形焦区获得了强度分布。与无像差计算结果的比较表明，当考虑球差时，会聚双合透镜会出现更高的峰值辐照度。给出了由准直高斯1.064μm激光束照射的透镜-轴棱锥组合中具有小顶角的轴棱锥的结果。
