Femtosecond fluorescence upconversion setup with broadband detection in the ultraviolet

We show a femtosecond fluorescence upconversion setup with broadband detection to measure time-resolved emission spectra in the 300-550 nm range, upon excitation between 250 and 300 nm, with a time resolution of 100 fs. We present time-resolved fluorescence emission spectra of 2, 5-diphenyloxazole in solution, which demonstrate the capabilities of the setup.
