Abstract: A laser light source, a submount for a semiconductor laser, and a method of providing a laser light source are provided. The laser light source includes a submount with first and second electrical contacts thereon and a trench there-between. A semiconductor laser is bonded to the submount by bonding third and fourth electrical contacts of the laser to the first and second electrical contacts, respectively. The third and fourth electrical contacts of the laser are arranged on opposite side of a laser active stripe, which is arranged over the trench of the submount.

Abstract: Heatsinking in laser devices may be improved via a device, including: a header disk having a first face with a circumference; a header post that is thermally conductive, and having: a second face connected to the first face coterminously with the circumference; a third face opposite to the second face; and a fourth face perpendicular to the second face and the third face; a lens holder, having a fifth face connected to the third face; and an optical subassembly connected to the fourth face and optically aligned with the lens holder. The device may also be understood to comprise: a header disk having a circumference; a header post that is thermally conductive, the header post having: an arc coterminous to a portion of the circumference; a mounting face, perpendicular to a plane in which the arc and the circumference are defined; and a bonding face perpendicular to the mounting face.
