The energy transfer mechanism of the mixed-dye laser using 9-methylanthracene-perylene system is discussed from the exper-imental results on the time-resolved fluores-cence characteristics of the acceptor dye. The fluorescence lifetime of the acceptor dye is elongated when a dye mixture solution is excited by the energy transfer process whose duration is longer than the excitation pulse. Rate constants of the energy transfer are estimated from the fluorescence intensity ex-pressed by a convolution integral. The energy transfer mechanism of this mixture is discuss-ed from the computed results.
