| Abstract | We report on CPA-free multipass amplification of ps-pulses in Holmium-doped yttrium lithium fluoride (Ho:YLF) crystals up to μJ pulse-energy-covering repetition rates from 10 kHz up to 500 kHz. The seed pulses at a wavelength of 2.05 μm are provided by a Ho-based all-fiber system consisting of a soliton oscillator and a subsequent pre-amplifier followed by a free-space AOM as pulse-picker. Considering the achieved pulse peak power at MW-level, this system is a powerful tool for efficient pumping of parametric conversion stages addressing the highly demanded mid-IR spectral region. © 2018 Optical Society of America under the terms of the OSA Open Access Publishing Agreement OCIS codes: (140.7090) Ultrafast lasers; (140.3580) Lasers, solid-state; (140.3280) Laser amplifiers; (140.3070) Infrared and far-infrared lasers.
