    FIGURE 1. A collection of fluorophores, excited by a short optical pulse (thick line), produces collective fluorescence emission that follows an exponential decay curve with 1/e lifetime τ (a). Regardless of the intensity of the excitation pulse, the decays from identical fluorophores all have the same characteristic lifetime τ (b).
