Tunable solid-state lasers based on PMMA doped with pyrromethene dyes

Tunable solid-state dye laser samples based on poly methyl methacrylate (PMMA) doped with PM567 and PM580 were prepared and the laser performances for them were studied in this letter. With pump repetition rate of 1 Hz and incident intensity of 0.1 J/cm², more than 30 nm wide tunable range had all been achieved using the two samples, and the highest slope efficiency of 52.08% was obtained in the sample PM567. To the best of our knowledge, the efficiency is the highest under the same condition so far. The linewidth for the laser was measured with the result of less than 0.2 nm. All results indicate that the high laser performance using tunable solid-state dye lasers based on PMMA doped with PM dyes can be achieved. A graph is presented.
