Flashlamp-Pumped, Organic Dye Lasers.
Abstract
The report describes an experimental program directed at investigating the potential of visible, organic dye lasers. The dye Rhodamine 6G was chosen for the most intense study, and solutions to a mathematical model of a dye laser were compared to the experimental results obtained with a laboratory device. This analysis combined with triplet lifetime measurements on anthracene show that dissolved oxygen in air-equilibrated solutions probably limits the triplet lifetime to approximately 0.0000001 seconds. Several lasers with linear flashlamps were investigated which operated in both single-shot and repetitive modes. Single-shot efficiencies as high as 0.35% were observed, and reliable operation at repetition rates up to 50 Hz was achieved. Two coaxial lamps were also tested with rhodamine 6G. The smaller of these lamps gave an efficiency of 0.48% and the larger yielded output energies in excess of 6 Joules. Cavity dumping experiments resulted in single pulses 5 nsec in duration, and we have observed laser emission at 8575 A from the dye 1,3,3,1',3',3'-hexamethyl-2,2'-indotricarbocyanine iodide. (Author)
