Multi-laser package using shared optics

An optical device comprising:

• a first laser chip and a second laser chip,
• the first laser chip including a first laser emitter to generate a first optical beam and a second laser emitter to generate a second optical beam,
• the second laser chip including a first laser emitter to generate a third optical beam and a second laser emitter to generate a fourth optical beam, and
• at least one of the first optical beam or the second optical beam being aligned, with a sub-micron level of tolerance, with at least one of the third optical beam or the fourth optical beam;
• and
• one or more lenses positioned in optical paths of the first optical beam, the second optical beam, the third optical beam, and the fourth optical beam.
