Research output: Chapter in Book/Report/Conference proceedingConference contribution


The use of self-pulsing GaInP laser diodes for use as excitation sources in fluorescence lifetime measurements was proposed. These lasers are extremely versatile due to their ability to produce single pulses that can be used as a conventional source for extracting lifetime information. They can produce pulse-trains with frequencies variable within a wide range by simply tuning the injection current of the laser. The pulses period can be matched to typical fluorophore lifetimes, which provides an opportunity to develop more conventional multiple-pulse techniques. The ability to extract temporal information via control of the excitation pulse could provide a route towards obtaining lifetime information using dc detection.
