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.

A semiconductor laser source includes a structured layer formed on a substrate made of silicon and having an upper face. The structured layer includes a passive optical component chosen from the group composed of an optical reflector and a waveguide. The component is encapsulated in silica or produced on a silica layer. At least one pad extends from a lower face of the structured layer, making direct contact with the substrate made of silicon, to an upper face flush with the upper face of the structured layer. The pad is produced entirely from silicon nitride, in order to form a thermal bridge through the structured layer. An optical amplifier is bonded directly above the passive optical component and partially to the upper face of the pad in order to dissipate the heat that it generates to the substrate made of silicon.

The present disclosure provides a laser projection component and a detection method thereof, and an electronic device. The laser projection component is applicable to the depth camera component and is configured to project a laser pattern. The detection method includes: obtaining the laser pattern; determining whether a preset identifier exists in the laser pattern; and determining that the depth camera component is abnormal when the preset identifier does not exist in the laser pattern.

The invention relates to a laser assembly (1) comprising a diode laser bar (2), a heat sink (4) and at least one cover (7). The laser bar is located between the heat sink and the cover. The heat sink and/or the cover is/are coated with nanowires (16) or nanotubes via which the contact between the laser bar and the heat sink and/or the cover is established.

A method for the production of a diode laser having a laser bar, wherein a metal layer having raised areas is used which is located between the n-side of the laser bar and the cover. The metal layer can be plastically deformed during installation without volume compression in the solid physical state. As a result the laser module can be reliably installed and a slight deviation (smile value) of the emitters from a centre line is achieved.
