1. A system, comprising:
a laser system comprising
a laser configured to output a fundamental frequency beam,
a first stage configured to receive an input of the fundamental frequency beam from the laser, to output from the laser system a first-stage harmonic frequency beam, and to output a first-stage residual fundamental frequency beam,
a second stage configured to receive an input of the first-stage residual fundamental frequency beam, and to output from the laser system a second-stage harmonic frequency beam, and
one or more beam splitters configured to split one or more of the first-stage harmonic frequency beam or the second-stage harmonic frequency beam into a plurality of harmonic frequency beams; and
a data writing system comprising a modulator configured to
receive the plurality of harmonic frequency beams from the laser system in parallel and
write parallel data to a substrate by modulating the plurality of harmonic frequency beams received from the laser system.
