We propose a new type of pump-probe method to investigate picosecond and femtosecond processes. This method utilizes the intensity correlation between two different temporally incoherent lights. It is demonstrated theoretically that the time resolution is determined by the correlation time independently of the pump and probe pulse widths. The validity of the theoretical consideration is confirmed by lifetime measurements for excited dye molecules.
