Abstract: A portable lighting apparatus is provided with a gallium-and-nitrogen containing laser diode based white light source combined with an infrared illumination source which are driven by drivers disposed in a printed circuit board assembly enclosed in a compact housing and powered by a portable power supply therein. The portable lighting apparatus includes a first wavelength converter configured to output a white-color emission and an infrared emission. A beam shaper may be configured to direct the white-color emission and the infrared emission to a front aperture of a compact housing of the portable lighting apparatus. An optical transmitting unit is configured to project or transmit a directional light beam of the white light emission and/or the infrared emission for illuminating a target of interest, transmitting a pulsed sensing signal or modulated data signal generated by the drivers therein. In some configurations, detectors are included for depth sensing and visible/infrared light communications.

Abstract: The embodiments described herein provide a device and method for an integrated white colored electromagnetic radiation source using a combination of laser diode excitation sources based on gallium and nitrogen containing materials and light emitting source based on phosphor materials. A violet, blue, or other wavelength laser diode source based on gallium and nitrogen materials may be closely integrated with phosphor materials, such as yellow phosphors, to form a compact, high-brightness, and highly-efficient, white light source. The phosphor material is provided with a plurality of scattering centers scribed on an excitation surface or inside bulk of a plate to scatter electromagnetic radiation of a laser beam from the excitation source incident on the excitation surface to enhance generation and quality of an emitted light from the phosphor material for outputting a white light emission either in reflection mode or transmission mode.

Abstract: The present disclosure provides an apparatus for generating fiber delivered laser-induced white light. The apparatus includes a package case enclosing a board member with an electrical connector through a cover member and a laser module configured to the board member inside the package case. The laser module comprises a support member, at least one laser diode device configured to emit a laser light of a first wavelength, a set of optics to guide the laser light towards an output port. Additionally, the apparatus includes a fiber assembly configured to receive the laser light from the output port for further delivering to a light head member disposed in a remote destination. A phosphor material disposed in the light head member receives the laser light exited from the fiber assembly to induce a phosphor emission of a second wavelength for producing a white light emission substantially reflected therefrom for various applications.
