Laser plasma acceleration (LPA) is a promising technology to drive the next generation of compact high brightness x-ray sources. Delivering the high electron beam quality, reproducibility and long-term stability required by applications is, however, still a major challenge. Here, we present a newly designed high-stability front-end for an LPA drive laser. The front-end consists of a white light seeded collinear OPCPA system, that is designed with the strict demands towards spatio-temporal beam quality and long-term stability in mind. We show first experimental results on the performance of the front-end that delivers highly stable >50uJ pulses with Fourier transform limit <25fs at a center wavelength of 800nm, suitable for seeding a high energy Ti:Sapphire laser system.
