Abstract

We present the results of the study of orientational relaxation of complex molecules on solutions, by means of degenerate four-wave mixing (three-wave mixing -TWM) of low-coherent "noise" laser light. This technique, where the time resolution is governed by the correlation time r, instead of the time duration of the light sources, has been applied for studying transient phenomena.'4 The correlation time of broad-band non-transform limited laser pulses can be short enough provide subpicosecond time resolution when studying the dynamics of physical processes.
