Time resolved nonequilibrium phonon dynamics in the nonradiative decay of photoexcited forsterite

Abstract
Information on the nonequilibrium phonon dynamics of the 225 cm−1 and 335 cm−1 modes on forsterite has been obtained using time resolved Raman scattering. The observed nonequilibrium phonon population is associated with the overall complex nonradiative decay following the excitation of the impurity ion.
