Abstract
Effects of spherical aberrations in converging and diverging lens-axic on doublets are investigated. Intensity profiles are obtained in the l ine and ring focal regions by numerically solving the Fresnel-Kirchhof f integral. Comparisons with aberration-free computations show that hi gher peak irradiances occur far the converging doublet when spherical aberrations are included. Results are presented for axicons with small apex angles in lens-axicon combinations illuminated by collimated Gau ssian 1.064-mu m laser beams. (C) 1997 Optical Society of America.
