Diffraction patterns for the sum CL + CR (top) and the difference CL − CR (bottom) images for the initial (a, d), +1.0 ps (b, e), and +100 ps (c, f) states. g The experimental (dots) and fitted (lines) orthoradial dichroic profiles for different pump-probe delay times showing a maximum at 90° and a minimum at 270° corresponding to a right-handed cycloidal winding of the domain walls. While the amplitude of the dichroic signal drops within a ps upon pumping and recovers afterwards, no significant angle shift in the fitted phase φ can be detected. The beamstop is located at an azimuthal angle of 90°.
