      abstract     = {Combining high peak and high average power has long been a
                      key challenge of ultrafast laser technology, crucial for
                      applications such as laser-plasma acceleration and
                      strong-field physics. A promising solution lies in
                      post-compressed ytterbium lasers, but scaling these to high
                      pulse energies presents a major bottleneck. Post-compression
                      techniques, particularly Herriott-type multi-pass cells
                      (MPCs), have enabled large peak power boosts at high average
                      powers but their pulse energy acceptance reaches practical
                      limits defined by setup size and coating damage threshold.
                      In this work, we address this challenge and demonstrate a
                      novel type of compact, energy-scalable MPC (CMPC). By
                      employing a novel MPC configuration and folding the beam
                      path, the CMPC introduces a new degree of freedom for
                      downsizing the setup length, enabling compact setups even
                      for large pulse energies. We experimentally and numerically
                      verify the CMPC approach, demonstrating post-compression of
                      8 mJ pulses from 1 ps down to 51 fs in atmospheric air using
                      a cell roughly 45 cm in length at low fluence values.
                      Additionally, we discuss the potential for energy scaling up
                      to 200 mJ with a setup size reaching 2.5 m. Our work
                      presents a new approach to high-energy post-compression,
                      with up-scaling potential far beyond the demonstrated
                      parameters. This opens new routes for achieving the high
                      peak and average powers necessary for demanding applications
                      of ultrafast lasers.},
