\email{[email protected]}  \keywords{shear wave, laser, soft solid, elastography}  \maketitle  When a laser beam of sufficient energy is incident on a medium, the absorption of the electromagnetic radiation leads to an increase of the local temperature. There is consequently a local dilatation, and the resulting displacement can propagate as elastic waves. Elastic waves can be separated in two components in a bulk: compression waves, corresponding to a curl-free propagation; and shear waves, corresponding to a divergence-free propagation. This phenomenon has been notably observed in metals. Measuring the compression and shear waves can be used as a method of inspection to reveal potential cracks in the solid.
