title: Self-referenced characterization of space-time couplings in near-single-cycle laser pulses.
abstract: We report on the characterization of space-time couplings in high-energy sub-2-cycle 770 nm laser pulses using a self-referencing single-frame method. Using spatially encoded arrangement filter-based spectral phase interferometry for direct electric field reconstruction, we characterize few-cycle pulses with a wavefront rotation of 2.8×1011rev/s (1.38 mrad per half-cycle) and pulses with pulse front tilts ranging from -0.33  fs/μm to -3.03  fs/μm in the focus.
