Laser-generating Irregularities

Caption

This microscope view of a film of the polymer DOO-PPV shows clumps of undissolved polymer power within the darker dissolved polymer material. Such irregularities are believed to create the tiny cavities that act as built-in, mirror-like resonators to produce what is known as "random laser" light, according to a new University study.
