      abstract     = {Within the FLASH2020+ upgrade, the pump-probe laser
                      capabilities of the extreme ultraviolet and soft x-ray
                      free-electron laser (XFEL) FLASH in Hamburg will be
                      extended. In particular, providing wavelength tunability,
                      shorter pulse durations, and reduced arrival time jitter
                      will increase the scientific opportunities and the time
                      resolution for the XFEL-optical laser pump-probe
                      experiments. We present here a novel concept for the
                      pump-probe laser at FLASH that is based on the
                      post-compression of picosecond pulses emitted from
                      high-power Ytterbium:YAG slab amplifiers. Flexible reduction
                      of the pulse duration is facilitated by spectral broadening
                      in pressure-tunable multi-pass cells. As an application, we
                      show the pumping of a commercial optical parametric
                      amplifier with 150 fs post-compressed pulses. By means of an
                      additional difference frequency generation stage, tunable
                      spectral coverage from 1.3 to 16 μm is reached with
                      multi-μJ, sub-150 fs pulses. Finally, a modular
                      reconfiguration approach to the optical setups close to the
                      free-electron laser instruments is implemented. This enables
                      fast installation of the nonlinear frequency converters at
                      the end stations for user operation and flexibility between
                      different instruments in the two experimental halls.},
