Paper Abstract

The dephasing time of the 1086 cm-1 mode in calcite has been measured as a function of temperature using a new innovative single shot streak camera technique that measures the phonon dephasing rate in real time. Phonon-phonon interaction models have been proposed and tested to explain the temperature dependence of the experimentally measured dephasing time. It is found that multiphonon splitting and scattering processes involving at least four phonons substantially contribute to the dephasing of the 1086 cm-1 mode in calcite.
