  • Molecular gas laser device with an improved output mirror means
    Patent number: 3936768
    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.
