Laser Beam Shaping with Membrane Deformable Mirrors
The performance of laser machining systems can often be improved by adjusting the intensity profile of the beam on the target. Shaping a laser intensity profile can be efficiently accomplished by adjusting the spatial phase of the beam before propagating the beam a distance to the target. Beam shaping can be accomplished with passive diffractive elements, but this technique is only capable of c...
متن کاملOptical Design of Laser Beam Shaping Systems
An overview of the history and current practices of laser beam shaping is presented. When diffraction effects are not important, geometrical methods for laser beam shaping (ray tracing, conservation of energy within a bundle of rays, and the constant optical path length condition) can be used to determine system configurations, including aspheric elements and spherical-surface GRIN lenses, whic...

متن کاملDevelopment and Testing of a Refractive Laser Beam Shaping System
A lens system for shaping a laser beam profile has been designed, built, and tested. It consists of two plano-aspherical lenses which convert a Gaussian input beam into a uniform irradiance output beam. The optical design is based on solving differential equations expressing conservation of energy and constant optical path length condition as the beam passes through the system. Experimental res...
