Semi-free As 2S 3 glass flakes undergo sub-mm scale anisot ropic deformation upon illumination of linearly-polarized cw bandgap light. The mechanism has been ascribed to photo induced birefringence, optical torque, and photo-induced flu idity. Quantitative measurements demonstrate that generated optical torque is ∼10 -20 Nm under a light intensity of 1 mW. This value combined with measured deformation rates for As 2S 3 cantilevers suggests a related photo-induced fluidity of 10 -1 P -1, which is much more fluidal (∼ten orders) than that reported in the conventional photo-induced fluidity. Reasons for this discrepancy are discussed.
