Few-cycle Relativistic Laser-Plasma Interactions at Kilohertz Repetition Rates

ORAL

Abstract

Relativistic few cycle laser pulses enable applications in high field physics, such as high harmonic generation or laser wakefield acceleration. We demonstrate efficient pulse compression of an output of a 36 fs laser pulse at 800 nm to 7 fs at the kilohertz repetition rate. Characterization of the on-target intensity shows that the overall wavefront is preserved, such that intensity is increased by $>$4. With proper dispersion correction optics, intensities of 10$^{19}$ to 10$^{20}$ Wcm$^{-2}$ can be achieved. Numerical modeling is also presented for the pulse compression and the corresponding few cycle relativistic interaction.
