Abstract
The choice of lasant for a space-deployed direct solar-pumped laser power system is strongly constrained by requirements such as solar spectrum utilization, chemical reversibility, and threshold pump energy. The t-perfluorobutyl iodide, (CF3)3Cl, or t-C4F9I was shown superior In some respects to t- C3F7I as a direct solar-pumped lasant.1 However, the laser kinetics of t-C4F9l are poorly understood, and experimental studies are lacking. This paper reports experimental measurements of the photoabsorption, threshold pump energy, and laser energy output of t-C4F9l in comparison with i-C3F7I for which the laser kinetics are better known.2,3
