(a) Schematic diagram of pump-probe technique. Time delay () between pump and probe pulses can be controlled by a mechanical delay line. (b) The fundamental principle of pump-probe experiments. Time varying refractive index changes of the sample induced by pump pulses were observed by detecting the intensity variations of probe pulses.
