ABSTRACT:
The present invention is a laser system that includes an acousto-optic device (24B) having an optical medium (40B) that maintains a substantially uniform index of refraction even when subjected to nonuniform thermal or mechanical stress. The acousto-optic device provides substantially distortion-free polarized output light that can be directed accurately to strike an intended target.
