Abstract
A gas-discharge laser having a Brewster window near at least one of the reflectors which is secured directly to the laser tube. The Brewster window is secured to a surface of the laser tube and a normal to the window makes an angle equal to the Brewster angle with the axis of the laser tube. The surface may be a slot in the laser tube or a recessed end face of the laser tube near a reflector. An advantage is that the Brewster window may have any convenient diameter and that the laser tube need not be drilled to form a cavity.
