The authors study the optical gain and saturation behavior in a blue-green-emitting
luminescent polymer gain medium. Based on the results of amplified spontaneous emission …

We demonstrate single-mode laser emission at 490 nm from a stable cavity based on a
methyl-substituted poly-para-phenylene-type ladder polymer. The laser emission is …

We have investigated near-infrared light amplification in a dye-doped polymeric waveguide
structure under optical pumping. Amplified spontaneous emission (ASE) at∼ 800 nm was …

Blue superradiant emission in thin polymer films with a low energy threshold, as reported
here, offers hope for the possible development of solid‐state electrically pumped polymer …

An optically pumped waveguide structure has been fabricated with methyl substituted
conjugated laddertype polyparaphenylene as the active material. The choice of the device …

Gain narrowing in optically pumped thin films, both neat and undiluted, of luminescent
conjugated polymers with different molecular structures was demonstrated. These results …

Light amplification at 6328 Å in a rhodamine‐B‐doped polyurethane thin film is observed.
The light‐guiding thin film is pumped transversely with a nitrogen laser. Superradiant light of …

We report on single pass optical gain and lasing measurements on a blue-emitting
copolymer, poly (m-phenylene vinylene-co-2, 5-dioctyloxy-p-phenylene vinylene) under 0.5 …

We report on a highly efficient laser based on a π-conjugated polymer blend system. The
gain material consists of phenyl-substituted poly-(p-phenylenevinylene)(PPPV) blended into …

The effective optical gain is measured in a polymethyl methacrylate plastic slab doped with
perylimide dyes and found to be positive. The experimental set-up is based on a single …
