Abstract
Abstract A high power multibeam laser having an improved output coupling mirror comprised of either a single mirror or a plurality of mirror elements attached to a mirror-supporting member. The inner face of the output coupling mirror, whether it be composed of a single mirror or a plurality of mirror elements, lies in a single flat plane which is perpendicular to the optical axis of the laser device. The outer face of the optical mirror may also be planar or may have a convex curvature with respect to the laser device.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
95 words
A high power multibeam laser system comprising: a plurality of oscillator tubes containing therein a laser medium and positioned approximately parallel to one another, at least one totally reflecting mirror disposed at one end of said oscillator tubes, an output coupling mirror disposed at the other end of said oscillator tubes, and means for applying pump energy to said laser medium for establishing a population inversion therein, and wherein said output coupling mirror comprises plural segmented mirror elements having at least the inner faces which face said oscillator tubes lying in a single flat plane.
