'Random lasing' in disordered materials was first shown over 20 years ago, but the mechanism by which it occurs is much debated. High-resolution imaging correlated to the excitation of random lasing from natural resonant cavities in conjugated polymers suggests there are many overlapping regimes and generation mechanisms involved.
