The two regimes have two opposite displacements \cite{undefined}. As previously described, the thermoelastic regime acts as local dipoles of force parallel to the surface. Thus, the medium stretches locally parallel to the surface, resulting two opposite displacements along X axis (parallel to the surface) and in an apparent displacement outside the medium along Z axis (normal to the surface). In the ablative regime, the point force in the medium displaces locally at the surface of the medium along Z axis, resulting in two weak opposite displacements along X axis. Initial displacement, displacement along Z axis,  as seenon on Z-displacement  at $t$=0.8 ms in Figure \ref{Figure2}, isclearly  negative, i.e., the displacement is inside the medium along Z axis, which is an indication of axis: this indicates  an ablative regime. This is confirmed by the observation of a disk of paler color of the same size as the beam diameter at the impact location of the laser on the phantom, which could correspond to a vaporization or a melting of a fraction of the material.  Moreover, at high amplitude, at the impact location of the laser beam on the phantom, a disk of paler color of the same size as the beam diameter can be observed. Some of the material has probably been vaporized or melted.  These arguments allowed to conclude to the ablative regime. Shear wave amplitude has been shown to be linearly dependent on laser beam power in thermoelastic and ablative regime, until plasma occurs regime. However,  at very high power higher amplitude  (about 10$^9$ W.cm$^{-2}$ in metals) \cite{scruby1990laser}. metals \cite{scruby1990laser}), a plasma occurs and lead to a non-linear amplitude of the displacement with laser energy.  The dependence of the generated shear waves on with  laser energy was then has thus been  investigated by increasing the laser beam energy from 10 to 200 mJ. Results are illustrated in Figure \ref{Figure4}-(A). We observe an linear relationship between shear wave amplitude and laser beam power, with a correlation coefficient of 0.9386. At an energy smaller than 50 mJ, shear wave amplitude becomeshowever  smaller than ambient noise. Due to this linear dependency, the plasma regime can be discarded.
