Abstract
A gas includes a housing having a symmetrical arrangement of upper and lower cooling members for removing heat generated in a gas-discharge excited by an electrode assembly. The electrode assembly is clamped between the cooling members and is itself essentially symmetrically arranged. The cooling members and the electrode assembly are mechanically isolated in the housing by a surrounding diaphragm-like arrangement that connects the cooling members to side-walls of the housing. An RF power-supply for supplying the electrode assembly is mounted on one of the sidewalls to avoid disturbing the symmetry of the cooling and electrode arrangements.
Claims23
A gas-discharge laser, comprising:
- a housing having first and second opposite longitudinal metal walls each thereof connected to third and fourth opposite longitudinal metal walls, the housing being closed by first and second end walls;
- and
- each of the first and second longitudinal walls having a rigid cooling portion surrounded by a flexible portion located between cooling portion and the lateral and end walls.
A gas-discharge laser, comprising:
- a housing containing a lasing gas mixture, the housing having first and second opposite longitudinal metal walls each thereof connected to third and fourth opposite longitudinal metal walls, the housing being closed by first and second end walls;
- first and second electrodes located in the housing spaced apart and parallel to each other and in thermal communication with respectively the first and second longitudinal walls;
- and
- an electrical power supply mounted outside of the housing on the third longitudinal wall and arranged to apply an electrical potential to one of the first and second electrodes, the power supply being thermally insulated from the third longitudinal wall.
A gas laser comprising:
- a housing, said housing having opposed top and bottom walls and a pair of opposed side walls extending between the top and bottom walls, said top, bottom and side walls being formed from a single metal extrusion;
- a pair of end walls for sealing the enclosure;
- and
- an electrode assembly located between and supported by the top and bottom walls, said electrode assembly being spaced from the side walls and the end walls, and wherein said top and bottom walls include a circumferential flexure portion located in the region between the electrode assembly and the respective side and end walls.
