Solid-state lighting is currently based on light-emitting diodes (LEDs) and phosphors. Solid-state lighting based on lasers would offer significant advantages including high potential efficiencies at high current densities. Light emitted from lasers, however, has a much narrower spectral linewidth than light emitted from LEDs or phosphors. Therefore it is a common belief that white light produced by a set of lasers of different colors would not be of high enough quality for general illumination. We tested this belief experimentally, and found the opposite to be true. This result paves the way for the use of lasers in solid-state lighting.
固态照明目前基于发光二极管（LED）和磷光体。基于激光的固态照明将具有显著优势，包括在高电流密度下具有很高的潜在效率。然而，激光发出的光的光谱线宽比LED或磷光体发出的光要窄得多。因此，人们普遍认为，由一组不同颜色的激光产生的白光质量不足以用于一般照明。我们通过实验对这一观点进行了测试，结果发现事实恰恰相反。这一结果为激光在固态照明中的应用铺平了道路。
