Abstract: of the Disclosure A gas laser with plasma chamber that can be quickly replaced by unskilled personnel. Plasma chamber can be replaced without need for optical realignment, one section of a mating mechanical coupler is secured to the nonconductive envelope of the demountable plasma chamber and is positioned in a predetermined spatial and angular position with respect to the electrodes, optical windows and the optical axis of the plasma chamber. The positioning of the mechanical coupler with respect to the electrodes, the windows and the optical axis is identical for each of the interchangeable plasma chambers. A separate base is provided with the other section of the demountable coupler fixed in a precise predetermined spatial and angular position with respect to a pair of mirrors mounted on the base. When a plasma chamber fails, it is easily replaced by merely disconnecting the old chamber from the base and inserting the replacement. The predetermined positions of the two coupler sections, one with respect to the electrodes and optical axis of the plasma chamber and the other with respect to the two mirrors, precisely locates the replacement chamber in position with sufficient accuracy to produce laser oscillations without elaborate adjustment.

Abstract: A gas laser is provided in which either or both of two "plug-in" modules, one of which comprises the plasma chamber and the other of which comprises the associated high voltage components and circuitry, can be quickly and easily replaced by relatively unskilled personnel without any need for optical realignment. This feature makes it possible to use sealed plasma chambers even in applycations where lasers are operated only intermittently and the sealed plasma chambers have limited operating life. With the elimination of the gas handling system, it becomes possible to manufacture compact, and in some important cases, portable and light weight lasers with replaceable plasma chambers and high voltage circuits. The invention is addressed to lasers operating at low to medium power output. In a preferred embodiment, each high voltage electrode of the plasma chamber includes a connector plate that extends through the envelope and removably engages a support plate of the module containing the high voltage pulse circuitry. These support plates are precisely positioned with respect to two resonator mirrors mounted permanently on a base structure, while the connector plates are precisely positioned with respect to the electrodes and windows of the plasma chamber. The positioning of the connector plates with respect to the electrodes, the windows and the optical axis is identical for each of the interchangeable plasma chambers. The module containing cont... the high voltage circuitry is releasable positioned on the base by two or more locator pins that retain it in a precise predetermined spatial and angular position with respect to the two mirrors. The position of this module with respect to the mirrors is identical for each of the interchangeable modules. The plasma chamber module thus "plugs in" to the high voltage module which in turn "plugs in" to the base structure. Either or both of the modules are readily exchanged with any other similar modules without optical realignment.
