The potential application of these results on a biological tissue was finally studied. The phantom was replaced by a chicken breast sample bought in the local grocery. Due to the absence of absorbing material like melanin or haemoglobin, the laser was diffused in a large area with a very small increase of temperature and couldn't induce elastic waves. Accordingly, a 5 mm diameter black disk was painted on the surface of the sample at the laser beam impact location.  Displacement amplitude maps along Y axis and Z axis 0.8, 1.6, 2.4, 3.2 and 4.0 ms after laser emission in the biological tissue are illustrated in Figure \ref{Figure5}. Shear waves propagated at a velocity of 5.5$\pm$.5 m.s$^{-1}$. It corresponds to a shear modulus of 30$\pm$5 kPa, which is a typical value for a relaxed muscle tissue \cite{sarvazyan1998shear}. The pattern is moreover very similar to the one presented in Figure \ref{Figure2}, suggesting similar involved phenomena. We found, again, a shear wave frequency of 500 $\pm$ 50 Hz.
