A 100Hz Ti:Sapphire Amplifier Delivering >700mJ Pulses for High Energy Laser Plasma Acceleration

Laser-plasma acceleration (LPA) [1] is rapidly evolving from proof-of-principle experiments to stable and reliable accelerator operation. The ability of LPA to deliver high-quality, high-energy electron bunches in a compact setup has been demonstrated in numerous experiments over the last two decades [2]–[4]. An important next step towards reliable accelerator operation is to increase the repetition rate from the current few Hertz to the kHz range. The main limitation of the repetition rate is currently the driving laser systems, which need to deliver pulses with ~100 TW peak power and excellent spatio-temporal pulse quality, which becomes increasingly difficult at high repetition rates.
