This work made during these three years deals with the study of optical properties of spin-state transition compounds. More precisely, we characterized the photo-induced transition of this complex. To make these studies, we have used two home-built experimental set ups based on time resolved pump-probe techniques. The relaxation process and the LIESST effect inside the thermal hysteresis loop was analysed with the first set up. Moreover, we have observed threshold effects for the photo-induced transition. We developed a second set up to have a better temporal resolution. For this, we used two lasers for the pump and probe. Thus, we could measure the low-spin to high-spin transition and the relaxation process. We have shown that thermal mech...
