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 ๐โ10^17โโcmโ3. We observed transverse energy transport of higher-order modes in the first โ12โโcm of the plasma...
Improved control of high intensity laser beam parameters on target recently enabled laser accelerated proton bunches with energies beyond 100 MeV, dose-controlled irradiation of biological samples, and the demonstration of FEL gain based on laser wakefield acceleration of electrons.
This presentation focuses on the chain of developments at the Petawatt laser DRACO at Helmholtz-Center...
