  • Safe laser light
    Patent number: 11316321
    Abstract: The present invention provides a device and method for a laser based light source using a combination of laser diode or waveguide gain element excitation source based on gallium and nitrogen containing materials and wavelength conversion phosphor materials designed for inherent safety. In this invention a violet, blue, or other wavelength laser diode source based on gallium and nitrogen materials is closely integrated with phosphor materials, such as yellow phosphors, to form a compact, high-brightness, and highly-efficient, light source with closed loop design features to yield the light source as an eye safe light source.
    Type: Grant
