Abstract
The ability to obtain a stable tunable picosecond pulse train from a synchronously pumped dye laser is shown to permit the use of modulated gain spectroscopy to study the lifetime, spectral, and concentration‐dependent behavior of fluorescent species. The fluorescence of rhodamine‐B in ethylene glycol at concentrations from 3μM to 5mM was observed over the range from 570 to 640 nm; a fluorescence lifetime of 2.2 ns was obtained.Keywords
