As solid-state dye lasers exhibit the attractive features of compactness being intoxic, and low cost, the development of tunable solid-state dye lasers is an area of active research. Solid state dyes based on polymethyl methacylate (PMMA) doped with new high efficiency pyrromethene-580 were prepared. First, the absorption and fluorescence of the samples were obtained. Pumped by the second harmonic of Q switched Nd:YAG laser, the output characteristics of the solid state dye lasers with different dye concentrations were studied. The central wavelength of the lasing emission peak increases with increasing dye concentration. The slope efficiencies of the samples were also obtained. The highest slope efficiency of 53.8% was obtained with dye concentration of about 2×104 mol/L. Pumped at 410mJ, the pulse energy of the solid dye laser reached 220mJ with the band width8nm.
