摘　　要：高功率超快脉冲激光应用广泛,包括精密工业加工、超快光谱学、强场物理学及军事应用等。光纤激光具有操作方便、散热要求低、光束质量好等优势。综述了近年来高功率超快光纤激光器的研究进展,包括新兴的被动锁模光纤激光技术及啁啾脉冲放大技术,以高功率超快光纤激光器在高次谐波产生中的应用为例,阐述了高能量光纤激光在非线性光学中的优势,对高功率超快光纤激光器的研究前景进行了展望。High-power ultrafast lasers have a wide range of applications, such as precise industrial processing, ultrafast spectroscopy, high-field physics, and military applications. Fiber lasers have the advantages of convenient operation, thermal load insensitivity, and good beam quality. The recent research progress of high-power ultrafast fiber lasers is reviewed, including the emerging passive mode locking and chirped pulse amplification technologies. The advantages of high-power fiber lasers on nonlinear optics are discussed via an example application, namely using high-power ultrafast fiber lasers to generate high-order harmonics. Further, the potential future research directions have also been prospected.
