Abstract
In this work, long-distance fluorescence lifetime imaging is realized by stimulated emission and electronic time delay control. Spatial coherence, as a result of stimulated emission, provides unattenuated fluorescence detection at long distance with low NA optics. The electronic trigger also provides a feasible way to change the pulse separation and probe the fluorescence lifetime in nano-second range. The lifetime of fluorophores is determined by measuring the stimulated emission signal at various the time delays between excitation and stimulation pulses. The characteristics of stimulated emission are investigated and the saturation condition is also presented.
