介绍了用于放大高峰功率飞秒脉冲的全光纤系统。在被动锁模掺铒光纤（EDF）激光器中产生的260-fs的脉冲，并使用EDF放大器系统放大。产生的脉冲的平均功率和峰值功率分别为215 mW和43.2 kW，脉冲宽度为42.3 fs。然后将放大后的脉冲耦合到保偏高非线性色散位移光纤中，产生跨倍频程超连续谱。光谱范围从980 nm扩展到2570 nm。据我们所知，该带宽是该波长区域中的最大带宽。
We present the all-fiber system for amplification of high peak power femtosecond pulses. The 260-fs pulses are generated in the passively mode-locked Er-doped fiber (EDF) laser and amplified using the EDF amplifier system. The average and peak powers of the generated pulses are 215 mW and 43.2 kW, respectively, and the pulsewidth is 42.3 fs. Then the amplified pulses are coupled into polarization-maintaining highly nonlinear dispersion-shifted fiber and octave-spanning supercontinuum is generated. The spectral range is widely expanded from 980 to 2570 nm. To the best of our knowledge, this bandwidth is the maximum one in this wavelength region.
