title: Gaussian-to-Bessel beam transformation using a split refracting system.
abstract: A two-element refracting system is designed to transform a Gaussian laser beam into a diffraction-free Bessel beam. The resulting input and output surfaces are almost spherical, which makes for easy implementation of the system.
