Recent developments in discharge-excited rare gas halide lasers
Abstract
A means for discharge stabilization in discharge-excited rare gas halide lasers operating in a quasi-CW mode is presented. The discharge configuration found to be most promising in laboratory investigations of small-scale devices is a transverse discharge between two dielectric sheets, which has been used successfully to excite a variety of rare gas-halogen mixtures at pressures near atmospheric. It is calculated that a rare gas halide laser can be pumped at levels greater than 10 to the 5th W/cu cm using frequencies of tens of MHz and a dielectric with a large product of the dielectric constant and the dielectric strength of the insulating material. Observations of the fluorescence of a XeF laser with two BaTiO3 sheets in the discharge channel reveal a good discharge stability in this configuration and support the feasibility of the transverse excitation technique.
