abstract = "We show time resolved spectroscopy measurements with femtosecond time resolution in LaVS3 crystal. Transient reflectivity reveals the existence of a preferential coupling between the photexcited electrons and the coherently excited A1g phonon mode. The time scale of this coupling is around 140 fs, whereas the time-scale of the interaction between the A1g phonon mode and the other phonons is around 400 fs. This phonon mode is damped in less then 2 ps. On longer time scale, the transient dynamics is characterized by a long-standing plateau of reflectivity, which can be due to either low inter-plane thermal conductivity or to a metastable state caused by carrier trapping in vanadium cluster.",
