| 520 | _ | _ | |a 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. |
