Abstract

Polymer membrane deformable mirrors offer a low-cost alternative to conventional technology in a wide variety of adaptive optics or laser beam shaping applications. In this paper we evaluate the suitability of two different kinds of polymer membrane deformable mirrors for laser machining. We present results showing that a 12.5-mm diameter nitrocellulose membrane fails near 400 microns of motion. We present results from a demonstration of a high peak power beam shaping and show a new compact laser beam shaping system using a polymer membrane deformable mirror. We evaluate the effect of Q-switched laser radiation on polymer membranes at 355nm and 1060nm.
