Abstract

It is an object of the present invention to provide A laser device of long life. In the laser device, light source is housed in transparent cooling vessel, and the vessel is filled with a cooling liquid which is circulated. The electrodes of the light source project out of the cooling vessel. Reflectors are provided outside the cooling vessel. The electrodes and the reflectors are out of contact with the cooling liquid. It is another object of the present invention to stabilize laser oscillation. A light source is housed in a first transparent cooling vessel. The first cooling vessel is filled with a first cooling liquid. A laser medium is housed in a second transparent cooling vessel. The second cooling vessel is filled with a second cooling liquid. A heat insulation layer is provided between the first and the second cooling vessels so that the first and the second cooling liquids are thermally insulated from each other.
