For many illumination applications, it is desirable for a laser beam to have a uniform irradiance distribution across its diameter. Refractive and reflective systems for reshaping a laser beam profile have been proposed and discussed for many years. One of the refractive systems consisting of two plano-aspherical lenses operates with high efficiency. Recently, a prototype of this two aspherical lens reshaping system has been made from CaF2. The performance of the prototype is presented in this paper. The optical design and analysis of this system also are discussed.© (1993) COPYRIGHT SPIE--The International Society for Optical Engineering.
