High luminous flux laser lighting using single-crystal Ce:YAG phosphor

Abstract

Laser lighting is rapidly becoming a viable alternative to LEDs in many applications. However, the high power density from the lasers put strict requirements on the phosphor materials used for downconverting the blue laser light. Here we demonstrate high efficiency white light generation using single-crystal Ce:YAG phosphors. More than 4700 lm is achieved using 30 W of incident blue laser light.
