    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.

    Abstract: A structured phosphor device includes a frame member comprising wall regions separating multiple openings of window regions. Further, the structured phosphor device includes a phosphor material filled in each of the multiple openings with a first surface thereof being exposed to an excitation light from one or more laser sources to generate an emitted light out of each window region. Additionally, the structured phosphor device includes an anti-reflective film overlying the first surface of the phosphor material. Furthermore, the structured phosphor device includes a substrate attached to a second surface of the phosphor material in each of the multiple openings. Alternatively, the structured phosphor device includes an array of phosphor pixels dividing a plate of single-crystalline or poly-crystalline phosphor material separated by optically reflective and thermally conductive walls. A dynamic lighting system based on the arrays of phosphor pixels for single or full color image projection is also disclosed.

    Abstract: A light source system or apparatus configured with an infrared illumination source includes a gallium and nitrogen containing laser diode based white light source. The light source system includes a first pathway configured to direct directional electromagnetic radiation from the gallium and nitrogen containing laser diode to a first wavelength converter and to output a white light emission. In some embodiments infrared emitting laser diodes are included to generate the infrared illumination. In some embodiments infrared emitting wavelength converter members are included to generate the infrared illumination. In some embodiments a second wavelength converter is optically excited by a UV or blue emitting gallium and nitrogen containing laser diode, a laser diode operating in the long wavelength visible spectrum such as a green laser diode or a red laser diode, by a near infrared emitting laser diode, by the white light emission produced by the first wavelength converter, or by some combination thereof. A beam shaper may be configured to direct the white light emission and an infrared emission for illuminating a target of interest and transmitting a data signal. In some configurations, sensors and feedback loops are included.
