Abstract
We report the generation of 10 μJ, ultrashort 97 fs pulses at 1 MHz by implementing a two-arm spectral coherent combining scheme in a fiber chirped-pulse amplifier (FCPA), allowing both gain-narrowing mitigation and large stretching ratio for energy extraction. Such architecture is able to support the amplification of large-bandwidth (>15 nm) together with high gain factor (>30 dB), allowing the generation of ultrashort sub-100 fs pulses at the output of a FCPA for the first time.
