Abstract
All-metal, RF-excited gas lasers 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 and electrodes and relies almost solely upon gas conduction and gas convection cooling, obviating compression heat sinking. The latter embodiment can permit gas flow between the laser cavity and tube gas chambers through elongated gaps or spaces at the corners of the cavity. Insulators support the electrodes in a few places and facilitate simple, low-cost assembly. The latter geometry is also well adapted for use in folded configurations featuring multiple lasing sections and a common discharge electrode.
