With the development of laser techniques, different kinds of lasers such as Nd: YAG laser, CO2 laser, and fiber laser are utilized for material processing, such as surface cleaning, color marking, and cutting. Laser cleaning and color marking becomes popular with the extension of electronics industry. Fiber lasers possess many interesting advantages over other laser systems such as high gain, high efficiency, good beam quality, and low thermal problems. In addition, Yb-doped (Rare-earth doped fiber) fiber laser’s role in fiber laser market becoming much more significant and its applications in industry bring many benefits.
