Extended Data Fig. 5: Pump and probe optical characterization of the customary light-induced Fréedericksz instability.
From: Sensitive vectorial optomechanical footprint of light in soft condensed matter

Experimental determination of the customary optical Fréedericksz instability for θ0 = 1. 6∘ and δ = 1.7 from the pump beam analysis (a) and from probe beam analysis (b). Set of selected power values that corresponds to the transverse intensity profiles shown in the top row: PA = 231 mW, PB = 235 mW, PC = 246 mW while Pth = 233 ± 1 mW . In panel (a), case C, the luminance has been enhanced on the right side of the image in order to better visualize the self-phase modulation intensity rings.
