Abstract:

Experiments are described in which the potential of dye vapors and HgBr as tunable visible lasers has been investigated. As a result of this three year effort, several significant results have been obtained. The B 2-sigma from X 2-Sigma absorption band of HgBr at 350 nm has been obtained and a near UV, optically-pumped HgBr laser has been demonstrated. The 502 nm HgBr laser has also been successfully flashlamp-pumped. Charge transfer absorption from HgBr B 2-Sigma at Lambda approx. 447 nm has been observed and the upper state tentatively identified. Intense, stable discharges inPOPOP and coumarin 6 vapor have been obtained in a UV preionized, transverse discharge device. Preliminary gain measurements reveal net absorption. Keywords laser visible tunable mercury bromide dye vapor optically pumped.
