Laser modulation plays a critical role in modern photonics, enabling precise control over the intensity, frequency, or phase of a laser beam. In applications ranging from optical communication to precision measurement and advanced imaging, achieving both high speed and long-term stability is essential. Fiber-coupled acousto-optic modulators (AOMs) have emerged as a key technology to meet these demands by combining the agility of AOMs with the convenience and reliability of fiber optics. https://www.cq-smart.com/how-to-correctly-use-and-operate-fiber-coupled-aom
