Short Wavelength Lasers for Fusion. Final Report, April 1, 1978-March 31, 1979

摘要

Two approaches to laser fusion drivers are examined: (1) an optically pumped Hg (6 exp 3 P sub 0 implies 6 exp 1 S) energy storage system; (2) metal vapor Raman compression. The feasibility of the first method was investigated by measuring the Hg stimulated emission cross section, which implied a saturation photon fluence in excess of the damage limit on existing window materials. The possibility of obtaining peak power magnification through stimulated Raman scattering was investigated by studying metal vapors as the appropriate Raman medium. The experiments indicate that a XeCl laser in conjunction with Pb vapor constitutes the most promising pump-compressor combination. Compression in excess of 6.7, with photon efficiencies of 42%, has been observed. (ERA citation 04:055379)
