Abstract:

The first program, Long Pulse XeCl Laser Frequency Down Conversion, was initiated following the encouraging Raman shifting results. The second program, Low Voltage, Low Energy X-Ray Preionization Source was undertaken after it was realized that the energy and power scaling of certain avalanche discharge excited lasers required a reliable, non-contaminating volumetric source of electron preionization as could be provided by moderate energy x-rays. In this initial experiment, the 308 nm UV output from the UCSD Xe Cl laser was focused into a lead vapor Pb heat pipe and the stimulated Raman emission in the blue-green was monitored. Research involved the refinement of the Raman down conversion experiment which consisted primarily of the improvement of the XeCl laser mode quality. This work and the results thereof are discussed in Section II. SEction III describes the results of an engineering program to build a reliable low energy X-ray source suitable for the preionization of rare-gashalide and mercury-halide discharge excited lasers.
