Vacuum fixture
An example method includes stacking a plurality of laser diode bars proximate an alignment plate. Each respective laser diode bar has a front edge through which the respective laser diode bar emits light. The alignment plate has a first side that provides a common plane for aligning the front edges of the laser diode bars and a second side opposite the first side. The alignment plate has a plurality of microholes extending between the first and second sides. The method also includes applying suction to the plurality of laser diode bars through the plurality of microholes. The suction draws the front edges of the laser diode bars against the first side of the alignment plate such that the front edges of the laser diode bars are aligned in the common plane. Conductive plates used to clamp the plurality of laser diodes therebetween may be aligned in a similar fashion.
