Random Laser Light

Caption: This microscope image shows a portion of a piece of an electrically conducting plastic or polymer film that has been bombarded by a pulse of green light from a conventional laser. The green light excites tiny cavities within the film to produce red-colored "random laser" light seen in the photo. University of Utah physicists have published a study explaining how this bizarre kind of laser works.
