双包层光纤激光器具有光束质量好、散热面积大等优点。介绍了三种获得脉冲输出的双包层光纤激光 器,即调Q光纤激光器、锁模光纤激光器及振荡放大脉冲光纤激光器。分析了它们的工作原理及关键技术,并对 国内外近期进展作了综述。
Double-clad fiber lasers have the advantages of good beam quality and large heat dissipation area. Three kinds of double-clad fiber lasers with pulse output are introduced, that is, Q-switched fiber laser, mode-locked fiber laser and oscillation amplified pulsed fiber laser. Analyzed their working principle and key technologies, and reviewed the recent progress at home and abroad.
