1. A multi-laser apparatus comprising:
a plurality of lasers that produce a plurality of beams of light;
a beam shaping component that receives each of the plurality of beams of light at the same position at a surface of or within the beam shaping component from different angles of incidence and is configured to generate from the plurality of beams of light an output beam of light having a predetermined intensity profile along a horizontal axis, wherein the beam shaping component consists of a single beam shaping lens and wherein light from each laser is propagated directly to the beam shaping component; and
a flow cell configured to propagate a sample in a flow stream, wherein the beam shaping component directs the output beam to the flow cell.
