In many Illumination applications, it is valuable that a light source can emit more lumens from a compact physical light-emitting area. This means that such a high-luminance light source can design an optical system with higher light intensity and a smaller beam angle. In the study, we used high-power blue laser pumping single crystal phosphor as luminescent cores, through novel optical designs such as compression optics, photon recycling, resonant cavity, etc., to reduce the gain of system étendue, improve the light output efficiency, and finally develop a laser-based white light module with ultra-high luminance performance.
