摘　　要：介绍该课题组近两年在光子晶体光纤超连续谱方面的主要研究成果,包括基于连续波泵浦研制全光纤化超连续谱源,利用级联一段高非线性正常色散光纤,通过光纤的受激拉曼散射效应实现超连续谱的平坦化;基于皮秒锁模光纤激光器实现全光纤化5 W输出超连续谱源;拉制一段145 m的锥形光子晶体光纤,利用自制的纳秒光纤激光器与锥形光子晶体光纤熔接,制备输出功率2.2 W的宽带超连续谱源;利用自制的网状光子晶体光纤和全固态光子带隙光纤,分别研究亚微米薄壁上偏振相关的超连续谱产生,以及基于四波混频效应产生的超连续谱.This paper presents recent work on supercontinuum source based on photonic crystal fiber.A CW-pumped supercontinuum source is designed.The flattening of the supercontinuum through stimulated Raman scattering is realized by cascading a long zero-dispersion wavelength high-nonlinearity fiber.A power of 5 W all-fiber supercontinuum source pumped by picosecond pulse fiber laser is achieved.By designing and drawing a segment of 145 m tapered photonic crystal fiber,a 2.2 W supercontinuum source,which is realized by splicing the fiber to a self-made nanosecond fiber laser,is made.Researches have also been made on supercontinuum generation for new kinds of fibers.Studies have been on the polarization dependent supercontinuum generation in a nanoweb microstructure,and on supercontinuum generation by four wave mixing in an all-solid photonic bandgap fiber.
