A fluorescence lifetime imaging (FLIM) system is described that utilizes a new compact and low-cost ultrafast laser source based on a gain-switched laser diode-seeded all-solid-state Cr:LiSAF regenerative amplifier that has been designed for this application. The pulse parameters of this source (0.5 μJ, 827 nm, 100 ps, 5 kHz) are shown to be appropriate to time-domain FLIM using a gated optical intensifier and the application to functional imaging of biological tissue is demonstrated, as well as the first evaluation of organic light emitting diodes using FLIM. © 2004 American Institute of Physics.
