All metal RF excited gas lasers (10, 20, 30) employing organic or inorganic insulating material including polyimide and aluminum oxide to provide a structurally homogeneous laser capable of low cost fabrication and broad temperature ranges suitable for military and commercial applications. A particularly novel embodiment employs an extruded housing (32) and finned electrodes (36) and relies almost solely upon gas convection and gas conduction cooling obviating compression heat sinking. The latter embodiment permits gas flow between the laser cavity (38) and tube gas chambers through elongated gaps or spaces (46) at the corners of the cavity (38). Periodically spaced insulator guides (40) support the electrodes (36) and facilitates simple, low cost assembly. |
