Laser action from two dipyrrinone dyes under flash-lamp pumping.
Two quasi-aromatic compounds, namely, two dipyrrinone dyes (Xanthoglow and Kryptoglow), exhibited strong fluorescence. Therefore they were tested for laser action under flash-lamp pumping. These two dyes outperformed Coumarin 540A and exhibited a high degree of photostability when dissolved in 1,4-dioxane. However, in all other solvents used, considerable photodecomposition was observed.
