Some laser action properties of a new Pyrromethene-BF<sub>2</sub> complex, 1, 3, 5, 7-tetramethyl-8-ethyl-2, 6-dicyanopyrromethene-BF<sub>2</sub> 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.
