We report on an ytterbium-doped fiber CPA system delivering millijoule level pulse energy at repetition rates above 100 kHz corresponding to an average power of more than 100 W. The compressed pulses have a pulse duration of 800 fs. To our knowledge, this constitutes the highest pulse energy ever extracted from a fiber based femtosecond laser system and nearly two orders of magnitude higher repetition rate than in previously published mJ-Ievel fiber CPA systems.
