Spectrally breathing femtosecond pulses from an Er-doped fiber laser

摘要

We report order-of-magnitude spectral breathing in a dispersion-managed Er-fiber laser with an intracavity bandpass filter. This is to our knowledge the highest of any laser reported. Pulse energy is 1.7 nJ, width is 110 fs. © 2008 OSA/CLEO/QELS 2008.
