title = "Time-resolved fluorescence of vegetation--Excitation intensity analysis",
abstract = "Time-resolved measurements of the laser-induced chlorophyll fluorescence emission of vegetation are described. The influence of the exciting laser pulse intensity on the overall fluorescence decay was studied for remote detection of plant stress. All the intensity measurements performed using picosecond laser excitation and a streak-camera detection system. For calibration a single-photon counting apparatus was used. The fluorescence decay of plants in steady-state conditions of photosynthesis is characterized by a medium lifetime of about 0.35-0.40 ns at a low-intensity excitation pulse. With an excitation pulse intensity above 1014 photons per cm2, the lifetime in the above-mentioned conditions decreases significantly. This shortcoming is interpreted in terms of exciton annihilation.",
