Time Resolved Raman

Our laboratories are set-up to perform picosecond resolution time-resolved incoherent anti-Stokes Raman scattering (TRIARS). This technique involves the generation of a non-equilibrium population of low energy excitations using an ultrashort laser pulse. The subsequent decay dynamics of this population are followed by measuring the Raman scattering from them due to a second time delayed ultrashort laser pulse. In our laboratory we are set up to excite and probe with either blue (370-450nm) or IR (700-990nm) radiation. In addition to the more standard methods of doing TRIARS we are set up to be able to measure TRIARS with co-linear parallel polarised pump and probe.
