Paint-on lasers and land-mine detection

Richard Jones: One of the many interesting features of semiconducting polymers is that they can be made to lase. By creating a population of excited electronic states, a situation can be achieved whereby light is amplified by the process of stimulated emission, giving rise to an intense beam of coherent light. Because semiconducting polymers can be laid down in a thin film from a simple solution, itís tempting to dream of lasers that are fabricated by simple and cheap processes, like printing, or are simply painted on to a surface.
