The principle of lasers is based on stimulated emission, a concept first proposed by Einstein in the early 20th century. The main process is as follows.

In cutting-edge optoelectronic fields such as optical communication, lidar, and photonic integration, semiconductor optical amplifiers (SOAs) serve as core devices for optical signal enhancement. Boasting advantages of small size, low cost, easy integration, and fast response speed, they are gradually replacing traditional optical amplification solutions and have become a key component supporting the development of high-speed optical networks and high-power optical systems. This article will analyze the working principles and full-scenario applications of SOAs in detail, and focus on discussing the technical characteristics, design challenges, and application value of high-power SOAs, helping to fully understand the core advantages of this "optical signal booster."

The difference between fiber lasers and semiconductor lasers lies in the different dielectric materials used to emit laser light.

Pump lasers are the "energy supply core" of laser systems. They inject light energy of a specific wavelength into gain media (such as erbium-doped fibers, solid-state crystals) to excite the media to produce stimulated radiation, and finally form a stable laser output. Their performance directly determines the power, efficiency and stability of laser systems.

At the Laser World Expo in Munich, TRUMPF, the world's leading industrial laser manufacturer, presented an innovative system solution designed to improve the quality and efficiency of laser welding processes. The solution integrates multiple sensors to monitor key points in the welding process in real time.
