1. A system comprising;
a laser;
an acousto-optic device;
a waveform generator configured to input a waveform into the acousto-optic device to generate an output laser beam comprising a plurality of angularly deflected laser beams;
a photodetector; and
a controller comprising a processor having memory operably coupled to the processor wherein the memory comprises instructions stored thereon, which when executed by the processor, cause the processor to:
determine an intensity profile of the output laser beam along a horizontal axis with the photodetector; and
adjust one or more parameters of a waveform inputted into the acousto-optic device in response to the determined intensity profile to generate an output laser beam having a modulated intensity profile.
