摘要

Spatio-temporal coupling characteristics of ultrafast laser pulse are quantitatively tailored. An asymmetric microstructure is induced in the focal volume when laser scans perpendicular to the direction of spatial chirp in fused silica. The tilted direction reverses when adding a Dove prism into the light path. The sign of pulse front tilt can be turned from positive to negative by changing the group delay dispersion by step. We reveal that tilted direction of microstructure depends on spatial chirp and the interplay between spatio-temporal chirp leads to the change of tilted angles.
