Abstract

original image

Graham Turnbull and co-workers report on p. 3205 that a luminescent concentrator based on a coumarin dye doped polymer film can be used to reduce the pumping threshold of polymer lasers. To achieve this effect, 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 is then used to pump the laser (the red laser emission can be seen at the left of the cover image).
