讲座摘要：High-power optical fiber lasers are widely used in various applications, such as industrial manufacturing, medical treatments, and advanced defense systems. To implement high-power fiber lasers, a range of fiber optic components with high power-handling capabilities are essential: for example, pump/signal beam combiners, isolators, rare-earth-doped fibers, cladding power strippers, end caps, fiber Bragg gratings, pump LDs, and so on. In this talk, I review our group's recent advances in the high-power cladding power stripper technologies based on hydrogen fluoride (HF) - free chemical etching.
