Abstract
A laser module includes an alignment plate having a template plate having a laser diode aperture and a photodiode aperture. A weld plate and a reflector are coupled to the template plate. The structure further includes a heat sink coupled to the alignment plate. A photodiode subassembly is mounted within the photodiode aperture and to the heat sink. Further, a laser diode subassembly is mounted within the laser diode aperture and to the heat sink. In the above manner, the photodiode subassembly, laser diode subassembly and reflected are precisely aligned.
