The operating characteristics of a flashlamp-pumped IBr laser were investigated to evaluate its suitability for solar-pumped laser applications. A peak power of 350 W/cm/sup 2/ at 2.7 ..mu..m was achieved at 12-Torr IBr pressure. At 500-J flashlamp energy, the IBr output saturated; a gain of 0.17% cm/sup -1/ was measured for IBr. Neon was found to be effective for enhancing the recombination of the photodissociation products. With neon as a buffer gas, the laser pulse length was extended to 53 ..mu..sec. The termination of the laser pulse, within the flashlamp pulse, is thought to be due to the temperature rise in the gas. Increasing the IBr initial temperature decreased the lasing output. At 300 /sup 0/C, output dropped to approximately one-half the room temperature value. The dominant quencher is thought to be atomic iodine. IBr was found to couple better to the flashlamp energy than C/sub 3/F/sub 7/I.
