The limitation to the amplification of femtosecond pulses by erbium-doped fibers owing to the soliton self-frequency shift may be overcome by using a dispersion-shifted fiber. We show that this result holds irrespective of the relatively large residual frequency-dependent chromatic dispersion that is associated with the pumping of the doping ions. Nevertheless, resonant dispersion may lead to temporal broadening and distortion of the amplified pulse.
由于孤子自频移导致的掺铒光纤对飞秒脉冲放大的限制，可以通过使用色散位移光纤来克服。我们表明，无论与掺杂离子泵浦相关的相对较大的与频率相关的残余色散如何，这一结果都成立。然而，共振色散可能会导致放大脉冲的时间展宽和失真。
