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

Ultra-narrow linewidth single-frequency fiber lasers (<1 kHz) are critical for applications like coherent optical communications, gravitational wave detection, and high-precision metrology. However, thermal noise in the fiber Bragg grating (FBG) and gain medium introduces phase fluctuations, ultimately limiting the achievable linewidth. https://www.cq-smart.com/ultra-narrow-linewidth-single-frequency-fiber-laser

Laser marking is the process of permanently marking a surface using a focused beam of light. It can be performed using different types of lasers, including fiber lasers, CO2 lasers, pulsed lasers, and continuous lasers.
