Optical amplification is a key technology in the field of optics and telecommunications, where it involves boosting and amplifying optical signals to enable long-distance transmission of data and information. Optical amplifiers are devices that use various methods, such as stimulated emission or semiconductor amplifiers, to increase the power of optical signals without converting them into electrical signals. This technology is essential for maintaining the quality and efficiency of optical communication networks, and has a wide range of applications in fiber optics, laser systems, and medical imaging.
