Laser beam shaping with digital micromirror devices (Conference Presentation)
Author(s): Andrew Forbes; Valeria Rodríguez-Fajardo

Paper Abstract

Laser beam shaping is a venerable topic and has seen implementation by a range of solutions, for example, static solutions in the form of refractive and diffractive optics, as well as dynamic solutions by adaptive optics and spatial light modulators. Recently geometric phase elements have come to the fore based on liquid crystal technology and metamaterials. All of these solutions are expensive and slow. Here we outline recent progress in the use of digital micro-mirror devices (DMDs) for real-time laser beam shaping and control. We demonstrate >1000 Hz creation of both scalar and vector beams of arbitrary design, and illustrate how to use this technology to mimic real-world beam perturbations such as thermal aberrations and turbulence.
