Abstract
A method and apparatus for convection control of metallic halide vapor density in a metallic halide laser (10). More particularly, an apparatus is disclosed wherein a reservoir (48) containing copper chloride (62), which in the exemplary embodiment is the metallic halide chosen, is heated so that the copper chloride is maintained in a liquid form. The apparatus includes a means for flowing a buffer gas, which in the exemplary embodiment is neon, over the liquid copper chloride to provide a mixture of copper chloride vapor and neon (72') above the liquid copper chloride. A conduit (50) for providing fluid communication between the reservoir (68) containing the copper chloride vapor/neon mixture and the laser (10) is also included. The copper chloride vapor density in the laser is related to the liquid copper chloride temperature and the neon flow rate through the reservoir (68). In accordance with a further feature of the exemplary embodiment, neon is also provided directly to the laser in order to provide a further means of controlling the copper chloride vapor density in the laser.
