Abstract
A supernarrowing laser spectrum is observed for mirrorless polymer waveguide lasers containing rhodamine B cored dendrimers. The moderate scattering from the aggregated dendrimers in the host polymer matrix is responsible for the mirrorless lasing. However, the long amplification path through the waveguide produces a directional beam and supernarrowing a spectrum in scattering lasers.Keywords
