摘要：

We report an experimental proof-of-principle of a method for recording femtosecond, time-resolved fluorescence spectra in the visible range. The method is based on a noncollinear parametric amplification in a beta barium borate crystal and provides time resolution of the order of 100 fs. We demonstrate that with this method, transient fluorescence spectra as wide as 6000 cm(-1) can be recorded in a single time-delay scan. Fluorescence decay dynamics and transient spectra of Coumarin 6 dye dissolved in aniline were measured to test the usefulness of the method. (C) 2005 American Institute of Physics.
