Acousto-Optic Modulators (AOMs) are robust, solid-state components designed for long operational lifespans. However, because they sit directly in the high-power optical path and rely on precise RF impedance matching, improper handling or environmental shifts can degrade performance. When diffraction efficiency drops or beam distortion occurs, a systematic troubleshooting approach helps engineers pinpoint the issue quickly and avoid unnecessary component replacement. https://www.cq-smart.com/5-common-applications-of-acousto-optic-modulator
