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 embodiments described herein provide a high-luminous flux laser-based white light source. A plurality of laser packages are arranged in an array pattern on a common support member. The plurality of laser packages each include one or more laser diode devices and a phosphor member. The phosphor member converts a fraction of the electromagnetic radiation from each of the laser diode devices to an emitted electromagnetic radiation and a white light is outputted.
