| 520 | _ | _ | |a Compact high-brightness electron beam sources are advantageous for industrial, medicaland scientific applications. Laser-plasma acceleration has the potential to meet thisneed, as it can provide acceleration fields that are orders of magnitude higher than inclassical linear accelerators based on modern radio-frequency technology, allowing formuch smaller accelerators. However, to make laser-plasma acceleration competitivewith modern radio-frequency linear accelerators, the quality of the driving laser pulses,on which the electron beam quality largely depends, needs to be improved. This thesiswas carried out in the framework of LUX at the Deutsches Elektronen-Synchrotron,a laser-plasma accelerator driven by the 200 TW peak power titanium-sapphire lasercalled ANGUS. At this facility it has been shown that the quality of the generatedelectron beam depends significantly on the position of the laser focus in the plasmaaccelerator and thus also on the central wavelength of the drive pulse. It has also beenshown that degradation and long-term effects in the current ANGUS laser front-endnegatively affect the stability of the accelerated electrons.This thesis presents the development of a novel seed laser for titanium-sapphirelaser-plasma acceleration drive lasers based on white-light generation seeded opticalparametric chirped pulse amplification. The focus of this work is on the passive andactive stabilization of the central wavelength after the parametric amplifier stage. Aphase-sensitive measurement method is applied to optimize the complex interactionbetween white-light generation and the parametric amplifier. When this method isused to examine the entire spectrum rather than just one parameter, such as the centralwavelength, the characteristics of the various sources of influence on the amplifiedspectrum become apparent. The engineered version of the seed laser delivers > 40 μJpulses at 1 kHz supporting a transform limited pulse duration of 23 fs. It was shownthat the relative central wavelength stability of < 2×10-4 is more than a factor of 2better than that of the previous front-end in ANGUS, which it replaced in July 2022.With the new seed laser the central wavelength stability, pulse duration and pulseduration stability of the entire ANGUS drive laser was significantly improved. Sincethe installation of the new seed laser, more than 50 successful electron beam timeshave been performed at LUX. In July 2024, another version of the same seed laser wasinstalled at KALDERA, which is a laser-plasma accelerator for demonstrating higherrepetition rates of up to 1 kHz. With the increased repetition rate, the phase-sensitivemethod can be applied there to assist in the development of electron beam sourceswith improved stability. |
