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.

A phosphor integrated laser-based light source includes a thermally conductive material arranged on a package base adjacent to a laser diode chip and an optically transparent material coupled to the thermally conductive material. A groove extends between the thermally conductive material and the optically transport material and is aligned to receive electromagnetic radiation from the laser diode chip. A wavelength conversion material is coupled to the optically transparent material and is configured to receive at least a portion of the electromagnetic radiation emitted into the groove and transmitted through the optically transparent material. A reflective material surrounds sides of the optically transparent material and the wavelength conversion material.

A diffuser lens includes a first annular lens segment and a second annular lens segment. The first and the second lens segments are concentric. A refractive index of the first and second lens segments in a cross-section along a plane including an optical axis of the diffusor lens is described by a refractive index profile which varies in a direction perpendicular to the optical axis. The refractive index profile includes a first sub-profile, which describes the refractive index profile of the first lens segment, and a second sub-profile, which describes the refractive index profile of the second lens segment. The first sub-profile transitions to the second sub-profile at an interface. These first and second sub-profiles have slopes with opposite signs.
