The world’s first white laser could revolutionize lighting and display tech

Incandescent bulbs have given way to CFL and LEDs, but these lighting technologies may be destined for extinction as well. A team of scientists at Arizona State University have developed a laser that can produce pure white light that is brighter and more efficient than even the best LEDs. Technically, thelaser itself isn’t white from the start, but the clever use of nanomaterials allows three colored beams to become one white beam.
