通过实验实现重复频率为168 MHz、中心波长为1040 nm、输出功率为270 mW的全正色散耗散孤子锁模光纤激光器；利用双包层掺Yb光纤对其进行放大，最大输出平均功率可达12 W。通过放大脉冲抽运高非线性光子晶体光纤(PCF)，最终获得光谱范围为600~2000 nm、输出功率为9.14 W的超连续谱，并对放大的皮秒脉冲产生超连续谱过程和机理进行定性解释。

A 168 MHz high repetition all-normal-dispersion mode-locked ring fiber laser is realized experimentally. The wavelength of the fiber laser is 1040 nm and output power is about 270 mW. The output pulses are amplified by using double cladding Yb-doped fiber and the max average output power reaches 12 W. By pumping the high nonlinear photonic crystal fiber (PCF) with the amplified high repetition pulses, the supercontinuum with average power of 9.14 W and spectrum range from 600 nm to 2000 nm are obtained. The mechanism of the supercontinuum generated by amplified pulses is qualitatively explained.
