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 strong  opposite displacements along X Y  axis (parallel to the surface) and in an apparent a weak  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 intwo  weakopposite  displacements along X Y  axis. Initial displacement along Z axis, as seen at $t$=0.8 ms in Figure \ref{Figure2}, is negative, i.e., the displacement is inside the medium along Z axis. Moreover, the displacement along Y axis (approx. 1.5 $\mu$m) is quite smaller than the one along Z axis (approx. 3 $\mu$m). We can then conclude to 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.
