Abstract
Abstract This is a laser that provides two or more output beams directly from the laser resonant cavity and includes an active laser element disposed in a resonant cavity consisting of a substantially totally reflective mirror at one end and a specially designed and oriented grating element at the other end which diffracts incident laser radiation into three or more orders depending upon the number of output beams desired.
