A luminescent concentrator , based on coumarin dye doped polymer film, is used to reduce the pumping threshold of polymer lasers. The edge of the luminescent concentrator is placed in contact with the surface of an MEH‐PPV distributed feedback laser. Intense green fluorescence from the edge of the concentrator film pumps the laser (red laser emission shown on left).
