Abstract

Summary form only given.We investigated a phenyl-substituted poly(p-phenylenevinylene) (PPPV) blended into a polymethylmetacrylat (PMMA) matrix in a ratio of 0.1% by weight. The absorption and photoluminescence spectra show a large spectral shift between absorption and emission that efficiently reduces reabsorption of the emission. A block of the polymer blend with polished end faces was placed into a resonator, consisting of a Littrow grating and an output coupler. The polymer laser was transversely pumped with a dye laser.
