This program will investigate continuous wave UV/VUV lasers operating           in the 150-300 nm region, where presently no such lasers exist.  A new          discharge will be used, the low pressure cyclindrical magnetron, to             pump rare gas metal vapor lasers: Ag+, Cu+, Pb+, Mg+ and Ga+.  The              magnetron discharge is considered to be especially well suited to rare          gas-metal vapor lasers.  Running on their own the magnetron lasers are          expected to provide milliwatts of single transverse mode UV, while the          use of auxillary low energy 0.1 KeV - 1 KeV electron beam pumping               should enable UV/VUV operation at the watt level.  Cold cathode,                grided cold cathode, and plasma cathode electron guns will be used for          low voltage 0.1 KeV - 1 KeV electron beam generation.  Detailed plasma          diagnostic studies will be made of both the independent magentron               discharge and the electron beam pumped magnetron plasma.  The energy            spectrum of the longitudinal electron beam will be measured along the           length of the magnetron discharge using newly developed Faraday probes          with apertures and grids.  Laser spectroscopy will measure sheath               electric fields and excited state densities versus operating                    conditions.  Plasma data will be compared to Boltzmann computer models          developed especially for the magnetron plasma.  Rate equation laser             models will be constructed and results compared to experimental                 optimization of these same lasers excited in the cyclindrical                   magnetron configuration.
