Patent number: 4752937Abstract: A gas laser has a coolable inner electrode for connection to a radio-frequency power source and a coolable outer electrode that is coaxial with and radially spaced from the inner electrode with an excitation space containing the gas to be excited in the radial space between the inner and outer electrodes. With a view to improving a laser of this type in such a way that excitation at higher power with retention of homogeneous discharge is possible, that gas decomposition is slower, and that any desired liquid coolant can be used regardless of the electrical conditions, the excitation space is radially bounded by two, tubular dielectric bodies which are coaxial with and radially spaced from each other.Type: GrantFiled: September 29, 1986Date of Patent: June 21, 1988Assignee: W.

Patent number: 4744091Abstract: A gas laser has (1) a reflecting body with a reflecting surface, (2) excitation space structure cooperative with the reflecting body for defining an excitation space which is open opposite the reflecting surface of the reflecting body, (3) devices for lasingly exciting a gas in the excitation space and (4) a mirror assembly. The mirror assembly has a mirror having a reflecting surface facing the opening in the excitation space. A radial flange is about the mirror with the reflecting surface of the mirror on one axial side of the radial flange. At least one spacer and, preferably three, circumferentially-spaced bars project from the excitation space structure and engage the radial flange substantially axially for supporting it at least one of axially slidably and tiltably. Bellows sealingly connect the one axial side of the radial flange to the opening of the excitation space structure and its other axial side to a backplate immovably connected to the spacer bar on the other axial side of the radial flange.Type: GrantFiled: October 21, 1986Date of Patent: May 10, 1988Assignee: W.
