We report on the conceptual design of an amplification chain based on Tm-doped gain medium [1], for solid-state, ultra-short CPA laser pulses, aiming at high-efficiency, kHz repetition rate, high peak power and kW-scale average power, with emission wavelength around 2 µm. A multi-pass configuration is presented, with three stages, with 4% doped Tm:Lu2O3 ceramic thin discs, lateral (edge) [3] pumping (EPDL) scheme with an output energy of  >500mJ from an input energy pulse of 1 mJ. The modelling of multipass extraction (at the 1kHz rep rate) and thermal load is also studied and discussed.
