ABSTRACT:
A linearly polarizing internal mirror type gas laser tube comprises a channel-shaped holder pair for axially compressively holding a Brewster plate in a hollow cylindrical space surrounded by an inside surface of a pipe. Each holder comprises a side wall pair and a connecting wall connecting the side wall pair. Each side wall has a pair of protrusions having a common axial end plane that provides the Brewster angle. The holders are brought into contact with the Brewster plate with the protrusions made to contact with corner portions of the plate. The side walls may have free ends spaced apart from the pipe inside surface. Alternatively, the side walls of at least one of the holders may have outwardly bent portions having free ends brought into contact with the pipe inside surface. It is readily possible to press shape the holders at low costs from a metal sheet.
