Laser Oscillation of Energy Transfer Solid-State Dye Laser with a Thin-Film Ring Resonator

Abstract
We fabricated an energy transfer solid-state dye laser with a thin-film ring 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 different wavelengths with one pumping source.
