Abstract
Three types of short-time measurements using temporally incoherent light instead of short pulses are described. Electronic dephasing in a polydiacetylene film, vibrational dephasing in dimethylsulfoxide liquid, and relaxation of optical Kerr effect in CS2 were observed with femtosecond time resolution. General applicability the ultrafast measument by various types of optical nonlinear processes using incoherent light was confirmed.
