Nuclear reactor excitation of XeF laser gas mixtures
Kinetic studies of the XeF laser system and other laser media have been studied under low-power (several kW/cc), long-pulse (100 to 200 microseconds) pumping conditions using fission-fragment pumping. Results include the measurement of fluorescence from excited states of KrF, N/sub 2//sup +/, and XeF and optical gain near 351 nm in gas mixtures containing Xe, NF/sub 3/, and a rare gas. Sandia's fast-pulse reactor facility (SPR III) was used for these experiments, in which a cell containing the gas mixtures is irradiated with thermalized neutrons. Energy deposition in the gas occurs through the interaction of energetic charged particles produced by neutron-induced fission events. Two pumping modes have been examined. One mode uses /sup 3/He as the rare gas, where charged particles from the /sup 3/He(n,p)/sup 3/H reaction excite the medium. Another mode uses fission fragments from /sup 235/U, which is coated on thin ceramic substrates, as the source of excitation. 7 refs., 10 figs.
