Some laser action properties of a new Pyrromethene-BF2 complex, 1,3,5,7-tetramethyl-8-ethyl-2,6-dicyanopyrromethene-BF2 complex are reported. This laser dye exhibits laser action in the green–yellow portion of the spectrum, and its laser action efficiency was ∼350% higher compared with Coumarin 545. Exceptional photostability of the new laser dye was observed when a mixture of 1,4-dioxane:heptane ratio of 1:4 was used as the solvent. Further, it is suggested that dye lasers can be upscaled to high average power output when surface-emitting laser diode arrays are used as pump (excitation) sources.
