Description
We report the experimental demonstration of a spatiotemporally engineered “chromatic Flying-Focus” laser pulse to enhance x-ray generation in relativistic Thomson scattering. Precise tuning of the group delay dispersion was used to match the velocity of the focus to the trajectory of a counter-propagating laser-wakefield-accelerated electron beam. This extended the Thomson-scattering interaction, leading to an enhanced x-ray yield. This approach allows for maximising the spectral density and brightness of the x-ray beam by orders of magnitude compared to equivalent focusing without chromatic control.
