Claim Text:
1. A laser diode assembly, comprising: a carrier base having a surface; a plurality of sub-mounts, each sub-mount in the plurality of sub-mounts attached directly or indirectly to the surface of the carrier base; a plurality of laser diode chips, each of the plurality of laser diode chips having two opposing bonding surfaces and an active layer between the two bonding surfaces, the bonding surfaces and the active layer being perpendicular to the surface of the carrier base, each of the two opposing bonding surfaces attached to one of the plurality of sub-mounts so that each of the plurality of laser diode chips including the active layer is vertically oriented relative to the carrier base, each laser diode chip having an active area at the end of the active layer, with a top relative to the carrier base that can emit radiation parallel to the surface of the carrier base when powered by an electric current; and wherein a distance of the top of the active area of each of the plurality of laser diode chips to the carrier base is not greater than half a pitch, plus or minus 10%, between adjacent ones of the plurality of laser diode chips in the laser diode assembly.
