1. An apparatus, comprising:
a plurality of singulated vertical-cavity surface-emitting laser dies each configured to output light; and
an optical arrangement configured to receive light from the vertical-cavity surface-emitting lasers and to output a plurality of output light beams, the optical arrangement including one or more collimators configured to provide one or more collimated beams by collimating the light from the plurality of the vertical-cavity surface-emitting lasers and sub-optics configured to produce the plurality of output light beams by beam shaping the one or more collimated beams.
