Abstract
A system and method of generating perceived white light by laser. The system comprises a laser, a phosphoric substrate, and optionally a diffraction grating. In one embodiment, a blue laser beam from the laser penetrates the phosphoric substrate to create perceived white light in a Gaussian distribution appropriate for emergency lighting. In another embodiment, the blue laser beam is split into multiple beams by the diffraction grating. The multiple beams penetrate the phosphoric substrate to create perceived white light in a Gaussian distribution appropriate for emergency lighting.
