Schematic drawing of an organic semiconductor laser sensor for explosive vapors. The divergent incoherent light from an InGaN lightemitting diode is converted into a coherent, directional laser beam by a nanostructured polymer laser. This compact and low‐cost laser can be used to detect few‐parts‐per‐billion concentrations of nitroaromatic explosivemolecules, exploiting a photophysical interaction between the gainmedium and surrounding vapor.
