We demonstrated 55-fs pulses from spectrally combining two chirped-pulse fiber channels operating at partially-overlapped spectral bands, with a pulse shaper incorporated in each channel. The spectral intensity and phase shaping in two fiber channels are coherently-spectrally synthesized by phase-synchronizing the two channels at the overlapped spectrum. To the best of our knowledge, 55 fs is the shortest pulse duration from a spectrally combined fiber system at one-micron Yb wavelength, and this work is the first demonstration of coherent spectral synthesis of two pulse shapers. This work provides a promising path toward high-energy, tens-of-fs fiber chirped-pulse amplifier systems.
