      abstract     = {Laser-driven plasma accelerators (LPAs) offer an efficient
                      and highly compact alternative to conventional
                      radio-frequency (RF) accelerators. This technology provides
                      the potential to extend the application range of
                      accelerators to a wider community, including science,
                      industry, and healthcare. However, significant research and
                      development is necessary to achieve the beam quality,
                      stability, average power, and energy levels required for
                      these applications. One of the key advancements needed to
                      reach this operation regime is the development of a suitable
                      driving laser source that can operate at kHz repetition
                      rates while providing pulses at peak powers in or close to
                      the TW range. Terawatt-class Ti:Sa lasers, representing the
                      most common driving lasers for LPA sources to date, are
                      limited to low repetition rates due to thermal issues. In
                      contrast, Ytterbium-doped Yttrium Aluminum garnet (Yb:YAG)
                      lasers are capable of supporting multi-millijoule energies
                      at high average powers and repetition rates. However, they
                      typically fall short of the peak power requirements for LPAs
                      due to their narrow gain bandwidth, which limits the pulse
                      duration to hundreds of femtoseconds. Combining Yb:YAG
                      lasers with efficient postcompression methods like
                      multi-pass cells (MPCs) could provide a promising solution
                      to this challenge, enabling high repetition rates and TW
                      peak powers through extreme-scale post-compression. In this
                      work, we aim to explore this new LPA-driving laser approach
                      with the main focus on developing a suitable laser source
                      using a relatively compact Yb:YAG Innoslab laser that
                      delivers 10 mJ pulses with 1.2 ps pulse duration at a 1 kHz
                      repetition rate. This dissertation further addresses
                      application-tailored optimization approaches and delivery of
                      the generated pulses for first electron acceleration tests,
                      aiming at demonstrating the first Yb-laser-driven LPA source
                      with expected electron energies in the few-MeV regime.},
