　　We have been developing a microscopy technique that simultaneously realizes the spatial resolution of STM and the temporal resolution of ultrashort-pulse laser technology, optical pump-probe (OPP)method [1-5].The combination of STM with optical technology has advantages to enable the analysis of photo-induced dynamics on the nanoscale as well as the realization of ultrafast time-resolved microscopy.In OPP-STM, a non-equilibrium carder distribution is generated using ultrashort laser pulses and its relaxation processes are probed by STM using the OPP method realized in STM.
