Abstract

Diagnostic and control of spatiotemporal couplings for laser-plasma acceleration drive lasers are discussed. Near-field angular dispersion and spatial chirp were measured by GRENOUILLE. The calculation of the pulse front tilt evolution is presented, and it is shown that the pulse front angle near focus can be controlled within 5 mrad, and finely tuned through temporal chirp.
