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…

Towards an in situ, full-power gauge of the focal-volume intensity of petawatt-class lasers
C. Z. He, A. Longman, J. A. Pérez-Hernández +7
About 50 years ago, Sarachick and Schappert [Phys. Rev. D. 1, 2738 (1970)] showed that relativistic Thomson scattering leads to wavelength shifts that are proportional to the laser…
