摘　　要： 光子晶体光纤(PCF)呈现出许多在传统光纤中难以实现的特性:可灵活设计的色散特性、增强的光学非线性特性、在极宽谱带内单模传输特性和增强的双折射特性等,使其从一出现便受到了广泛关注并成为近年来光学与光电子学研究的一个热点,在飞秒激光技术中得到了广泛的应用并极大地提高了锁模光纤激光器的输出水平。尤其以掺增益介质的双包层光子晶体光纤为代表的新型光纤激光技术的出现极大地推动了飞秒激光技术的普及化。阐述了近年来基于光子晶体光纤的飞秒激光振荡器、放大器方面的研究进展及其前沿应用。 It has been shown by intensive research activities in the optics and optoelectronics fields that many novel properties unimaginable with conventional optical fibers can result from the holey structure in photonic crystal fibers （PCF）, including flexible design of dispersion, enhanced nonlinearity, endlessly single mode operation, and high birefringence. Photonic crystal fiber has been successfully applied in femtosecond laser technology and pushed the output performance of femtosecond fiber laser to match with the solid-state laser system. A review of recent work on high power femtosecond photonic crystal fiber laser oscillator, amplifier and their applications are proposed. Feasible scenario in future applications of high pulse energy large mode area photonic crystal fiber lasers will be come soon.
