Abstract:

Three types of excitation have been explored including soft x-ray pumping from laser-produced plasmas, electron beam pumping, and pulsed jet discharge pumping. Using the laser produced plasmas, new quasimetastable states of barium which radiate in the XUV have been explored and new VUV radiating molecules have been produced. Electron beam pumping has also resulted in the formation of ionic excimer molecules which radiate in the VUV, and considerable kinetic studies were performed to examine the feasibility of producing a VUV laser by this technique. This included the development of the necessary technology to allow electron beam pumping of reactive vapors at approximately 700 degree C and still maintaining compatibility with VUV detection equipment. Using the third excitation technique, pulsed jet discharge pumping, the formation of highly excited ions from the sputtering of low vapor pressure materials used in the pulsed jet nozzle were studied.
