We setup an ultrafast noncollinear optical parametric amplification system for fluorescence spectral dynamics study. The simultaneous broadband amplifying ability makes it suitable as an ultrafast spectrometer with femtosecond time-resolution. By real-time fluctuation correction, femtosecond fluorescence spectra are obtained efficiently by a single scan. With this technique, the solvation dynamics of DCM dye in four solvents are measured to demonstrate the performance of the system. We show that this ultrafast time-resolved spectrometer is very useful and efficient in studying ultrafast spectral dynamics.
Research highlights
► Femtosecond fluorescent spectrometer based on non-collinear parametric amplification.
► Full fluorescence spectral decay at femtosecond time resolution is achieved by single temporal scan.
► Spectral dynamics can be observed and studied directly in this spectrometer system.
