The resulting displacement amplitude maps along Z axis 1.0, 1.5, 2.0, 2.5 and 3.0 ms after laser emission in the phantom are illustrated in Figure \ref{Figure2}, for two laser beam energies (10 and 200 mJ). A typical shear wave pattern can be recognized: symmetry for the Z-displacement \cite{undefined}. The displacement Displacements  reached an amplitude of 0.01 $\mu$m for the 10 mJ laser beam and 2 $\mu$m for the 200 mJ. The displacement They  propagated at a velocity of 5.5$\pm$0.5 m.s$^{-1}$, which is a typical value for shear wave, and far lower than usual compression wave velocity, about 1500 m.s$^{-1}$ in soft tissues. Supposing the medium density $\rho$ of 1000 kg.m$^{-3}$, it corresponds to a shear modulus of 30 kPa, which is in range of the expected value of the phantom. Shear wave frequency was equal to 500 $\pm$ 50 Hz. A careful observation indicates two different patterns. At low energy, first displacements are along negative Z and we distinguish three half cycles. At high energy, first displacements are long positive Z and only two half cycles are distinguished.
