The pump-probe technique is an ultrafast spectroscopy method of detecting the dynamics of energy carriers such as electrons, phonons, and holes with transient thermal reflectance measurement. A laser beam is divided into a pump beam and probe beam with different wavelength or polarization and time delay. According to the transient reflectance result, this method could be applied to investigate the interaction between electron-phonon and electron-electron coupling with a high temporal resolution on the order of 10 femtoseconds.
