Abstract

Amplified spontaneous emission (travelling-wave lasing) was achieved for a series of arylene-vinylene polymers (PAy). Wave-guiding neat films on glass substrates were used. The samples were transversally pumped with picosecond laser pulses (wavelength 347. 1 5 nm, duration 35ps). The laser emission occurred in the wavelength region between 480 nm and 650 nm. The travelling-wave lasing was identified by spectral narrowing, temporal shortening, and threshold behavior of light emission.
