Princeton Develops Organic Laser

Researchers at Princeton University in New Jersey have developed a laser from vacuum-deposited organic thin-film materials. Organic lasers have been eyed for years as a possible replacement for inorganic semiconductor diode lasers. Potential advantages of organic materials-based lasers include a wider array of colors, tunability and lower cost. The discovery emerged from research on organic light-emitting diode technology done in conjunction with Universal Display Corp. of Bala Cynwyd, Pa. The company has demonstrated transparency for organic displays and the potential for high-resolution, full-color displays using Universal Display's vertically stacked pixel architecture.
