T = T_0 + \frac{\gamma}{S \rho C} E \exp(-\gamma r)  \label{eq:eqTemperature}  \end{equation}  where $T_0$ is the initial temperature of the medium.  The local increase of temperature can lead to two main effects creating elastic waves: (1) thermoelastic expansion and (2) ablation of medium. In metals, transition from first to second regime occurs approximately about 10$^7$ W.cm$^{-2}$. This is equal to the energy of the laser we used, so the predominant regime in our experiment cannot be determined yet.
