Towards direct spatial and intensity characterization of ultra-high intensity laser pulses using ponderomotive scattering of free electrons
A. Longman, S. Ravichandran, L. Manzo +12
Spatial distributions of electrons ionized and scattered from ultra-low pressure gases are proposed and experimentally demonstrated as a method to directly measure the intensity of…

Imaging electron angular distributions to assess a full-power petawatt-class laser focus
Smrithan Ravichandran, Marine Huault, Roberto Lera +5
We present a novel technique to assess the focal volume of petawatt-class lasers at full power. Our approach exploits quantitative measurement of the angular distribution of electr…
