Fig. 3: Static and time-resolved SHG polarimetry.
From: Ultrafast simultaneous manipulation of multiple ferroic orders through nonlinear phonon excitation
Polar plots of the equilibrium SHG intensity, I, are shown for (a) p-polarization detection and (b) s-polarization detection (open circles). Polar plots of the pump-induced change of the SHG intensity, ΔI, are shown for (c) p-polarization detection and (d) s-polarization detection at the maximum of the pump-probe response (open squares). In all plots, solid lines are fits of the SHG intensities, composed of the ferroelectric contribution (grey areas) and the antiferromagnetic contribution (red areas). Both the ferroelectric and antiferromagnetic contributions show an enhancement following the resonant phonon excitation.
