Petawatt lasers for particle acceleration at HZDR Dresden — •Ulrich Schramm — Helmholtz-Zentrum Dresden-Rossendorf, Dresden, Germany

Focal intensities far beyond 10¹⁸ W/cm² have allowed for the development of compact laser plasma based particle accelerators. Applications are envisioned in the fields of cancer therapy or ultra-fast probing with energetic photons. However, such applications require peak power in the Petawatt range as well as average power.

Here, the development and status of the two Petawatt projects at the HZDR will be presented, one based on the upscaling of established Ti:Sapphire technology, the other on the energy efficient approach of exploiting directly diode laser pumped Yb:CaF₂. Special emphasis will be given on diagnostics concepts that allow for online monitoring of crucial parameters of these pulses as, e.g., temporal pulse contrast.
