Demonstration of Coherent Random Lasing in Optically Thin Quasi-2D Lead-halide Perovskite

Random lasing in organic-inorganic lead halide quasi-2D perovskite was observed by measuring lasing threshold, spectral narrowing, spectral correlations and critical volume. The photon transport mean free path is found to be comparable to the lasing wavelength, suggesting a hybrid localized-diffusiv...

Summary:Random lasing in organic-inorganic lead halide quasi-2D perovskite was observed by measuring lasing threshold, spectral narrowing, spectral correlations and critical volume. The photon transport mean free path is found to be comparable to the lasing wavelength, suggesting a hybrid localized-diffusive lasing regime.
