Using an Acousto-Optic Modulator as a Fast Spatial Light Modulator

Name: Work Video:
Duration: 3 min 30 s
Description: We generate arbitrary 1-dimensional spatial profiles in a laser pulse by mapping the temporal electrical waveform sent to an acousto-optic modulator (AOM). The AOM can be therefore used as a spatial light modulator with 45 μm pixel pitch, fast refresh rate, and high damage threshold.
