Laser oscillation of energy transfer solid-state dye laser with a thin-film ring resonator

We fabricated an energy transfer solid-state dye laser with a thin-film rin g resonator. We combined several organic dyes, such as stilbene 3, coumarin 153, rhodamine B, and cresyl violet. The mixed dyes were embedded into the xerogel thin film by the sol-gel method. We pumped the dye molecules with a pulsed Nd:YAG laser third-harmonic generation (THG). Using the mixed-dye doped thin-film ring resonator, we obtained laser oscillation at four diffe rent wavelengths with one pumping source.
