Abstract

Spherical aberration is a common phase distortion that occurs in optical elements. An optical beam passing through an element that has spherical aberration will accrue a quartic phase term. Here, we provide an analytical analysis of the effect of the quartic phase on the beam quality factor of Laguerre-Gauss beams. We find that the beam radius is a critical parameter in determining the effect of the aberration on the quality of the laser beams.
