Analytical Treatment to Minimize the Aberration in Concentric Lenses Employed in High-Power Irradiation Applications


In this work, an analytical treatment to minimize the aberration (especially spherical) in concentric lenses was presented. The lenses concerned in this treatment are supposed to be graded-indexed optical elements of homogeneous surfaces. Spherical aberration is, contradictive to other types of aberrations, found possible to be eliminated in such optical elements as it is highly interested in high-power irradiation applications like laser-plasma interaction, microfabrication and fine-scaled metrology.
