Paper Abstract

A rectangular laser beam of uniform intensity is very suitable for laser photochemistry. In this paper, we propose a beam-forming system that consists of two deformable mirrors. One of the mirrors changes the beam intensity and the other compensates for phase distortion. We simulate the beam-forming property using a Fresnel equation solved by a Fourier transformation. We reshaped a Gaussian-like He-Ne laser beam into a beam with a more uniform intensity profile by a simple deformable mirror.
