We have proposed a novel transient absorption technique, Randomly-Interleaved–Pulse–Train (RIPT) method in which a picosecond super continuum light source is used as probe light. We developed a measurement system with a picosecond pulsed laser as pump light, and we observed dynamics of various samples which have not been well examined because of the difficulties in measuring nanosecond time region.
