ABSTRACT:
A mounting assembly for supporting a Brewster window and mirror to intercept a laser beam at the end of a gas laser envelope includes an elongated tubular member having one end opening into the gas laser envelope and an opposite end closed by the Brewster window. A rigid housing supporting the mirror is joined to the tubular member close to the end having the Brewster window by a flexible sealed joint that permits limited movement of the housing relative to the tubular member generally along the length of the tubular member while inhibiting flow of contaminants from the exterior into the passage formed by the rigid housing between the Brewster window and mirror. A seal is placed between the rigid housing and mirror to inhibit flow of such contaminants into the passage from the mirror location. A mounting structure joins the rigid housing to the gas laser envelope to secure them together and includes an adjustment mechanism that permits the housing to be moved relative to the envelope for adjusting the angular orientation of the supported mirror relative to the intercepted laser beam.
