Аннотация
We report mirrorless lasing in thin films of poly(2,5-dioctyloxy- p -phenylenevinylene) (DOO-PPV), that we identify as superradiance. We have measured the characteristic properties associated with this phenomenon including spectral narrowing, polarization memory, thickness and intensity dependencies. From the measurements of picosecond transient gain and loss in DOO-PPV we conclude that DOO-PPV films are excellent candidates for solid state lasers.
