Random Laser Action in Dye-Doped Polymer Media with Inhomogeneously Distributed Particles and Gain

The properties of random lasing are investigated for bubble-structure (BS) dye-doped polymer random media in which non-scattering and no-gain regions are distributed. Experimental results demonstrate that, for BS random media, spectral narrowing and a decrease in the number of spectral spikes occur...
