Laser wakefield acceleration (LWFA) of electrons occurs when an intense short laser pulse focused in an underdense plasma drives in its wake a plasma wave with an amplitude large enough to trap and accelerate electrons. Relativistic electron bunches are easily obtained through this mechanism and have given rise to a large number of studies and publications. Despite these efforts, the...
Very important results with the first observation of structured light laser driven plasma wave with femtosecond relativistic electron microscope. A path toward dephasing free accelerator. Paper under review. Aaron Liberman is one of my best PhD student and an outstanding speaker. Paper with referees.

We measure the high-intensity laser propagation throughout meter-scale, channel-guided laser-plasma accelerators by adjusting the length of the plasma channel on a shot-by-shot basis, showing high-quality guiding of 500 TW laser pulses over 30 cm in a hydrogen plasma of density 𝑛≈10^17 cm−3. We observed transverse energy transport of higher-order modes in the first ≈12 cm of the plasma...
Proton beams produced from plasma accelerators have recently reached 150 MeV beam energy. This is considered a crucuial milestone on usability of this technology for cancer treatment. The technical results at HZDR are presented, further advances are discussed and an outlook to applications is presented.
