Acousto-optic modulator

An acousto-optic modulator (AOM) is a device that uses sound waves to control light. When sound waves pass through a crystal, they create changes in the material's density that can bend or scatter light beams. This allows the AOM to switch the light on or off, change its intensity, or alter its frequency. These modulators are commonly used in laser applications, telecommunications, and optical signal processing, enabling precise control of light for various technologies, including lasers in medical devices and optical communications.
