Abstract
Solid-state dye laser materials based on polymethyl methacrylate (PMMA) doped with different concentrations of Coumarin 540A were prepared. The absorption, fluorescence and blue-green lasing spectra of the samples were obtained and studied in this latter. With the third harmonic generation (THG) of Q-switched Nd:YAG laser pumping the samples longitudinally, the highest slope efficiency is 12.8%, which is achieved in the sample with a dye concentration of 1.0 × 10-3 mol/L.
