The way FRET takes place in dye-doped biopolymer complexes is studied by time-resolved measurements. The efficiency of the energy transfer is controlled by the relative concentration of the donor/acceptor species and described with a distribution of processes. Amplified spontaneous emission in the system and its evolution with the FRET efficiency is monitored.
