1. A method of operating a multi-channel acousto-optic modulator (AOM), comprising:
applying a first radio frequency (RF) tone, using a first waveform generator, to generate a first acoustic wave in at least a first channel of the multi-channel AOM, wherein a portion of the first acoustic wave interacts with a second channel of the multi-channel AOM to cause a crosstalk effect on the second channel; and
applying a second RF tone, using a second waveform generator, to generate a second acoustic wave in the second channel, wherein the second acoustic wave reduces or eliminates the crosstalk effect caused by the portion of the first acoustic wave within the second channel.
