| Résumé |
|
Controlling material properties with light pulses represents one of the next great challenge in material science. To achieve this goal, one needs to impact the material on the relevant time scale for controlling electronic and phononic properties. Targeting this challenge becomes possible thanks to the emerging field of photo-induced phase transition when a femtosecond light pulse interacts with the system. Along this line, we demonstrate the possibility to perform femtosecond optical spectroscopy under control thermodynamical environment. This new experimental setup includes a very precise pressure control between 1 and 6 kbar. These experimental results clearly demonstrate an effect of hydrostatic pressure onto the out-of-equilibrium photo-response of V2O3. The main feature is a blue shift of the Brillouin frequency that correlates with an increasing speed of sound.
