Abstract

Four new BF₂-complex laser dyes have been synthesized and spectroscopic and laser studies have been performed. The 8-cyano-pyrromethene-BF₂ complexes showed the best performance with red emission and slope efficiencies as high as 48% when pumped with a frequency doubled Nd:YAG laser. Additionally, three previously known pyrromethene-BF₂ complex dyes obtained from a commercial source were tested. These dyes showed a relative efficiency of greater than 80%, with one (PM-580) displaying a slope efficiency of 89%. This efficiency is the highest reported for any dye laser.
