Paper Abstract

Recently laser technologies are expanded widely among various applications of optical devices. Regarding unique properties laser sources are used in industrial systems, in medicine, in a variety of laboratory equipment, etc. Large number of technical applications requires laser beam reshaping, which presuppose redistribution of optical power in the beam cross-section; particularly to form a flat-top beam with uniform intensity distribution. Traditional inverted lens telescopic systems purposed for the light collimation do not allow to achieve the laser beam reshaping. For this case is possible to use more complicated kind of lens surfaces, such as aspherical ones, or freeforms (both lens and mirror optical systems), microlens arrays and other approaches. Current work describes the optimization model of laser beam reshaping optical system based on aspherical (conic) optics, using Zemax software. Single and two-lens telescopic systems were investigated to reach specified characteristics, results of this studies are shown.
