Acousto-optically (AO) Q-switched fiber lasers have become a cornerstone in applications that require high-energy, pulsed laser output. These systems are widely used in materials processing, remote sensing, and precision measurement due to their stability and energy efficiency. One of the central goals in fiber laser design is to scale pulse energy while maintaining pulse quality. Achieving this requires careful management of the gain medium, Q-switch parameters, and fiber characteristics. https://www.cq-smart.com/acousto-optic-modulators-for-q-switch-in-lasers
