Abstract

Time resolved four-wave-mixing has proven to be a useful tool for studying the spatial transfer of energy in optically active materials. When spatial migration of energy occurs, it is found that the transient grating decays with a lifetime which is less than half the fluorescence lifetime of the excited species. By studying the dependence of the decay rate on the grating periodicity, a diffusion constant for the energy transfer can be obtained.
