Tests show new kid on block — diode lasers — eventually could challenge LEDs for home and industrial lighting supremacy The human eye is as comfortable with white light generated by diode lasers as with that produced by increasingly popular light-emitting diodes (LEDs), according to tests conceived at Sandia National Laboratories. Both technologies pass electrical current through material to generate light, but the simpler LED emits lights only through spontaneous emission....
