Sample and pump-probe ATR experiment.
(a) Photoisomerization and thermal relaxation of DR1 molecule. (b) Multilayer sample consisting of a Ag layer, a fluorofore Cytop layer, and a DR1-doped PMMA layer, deposited on a SF10 substrate. (c) Kretschmann configuration of ATR measurements with pump (blue) and probe (red) beams.
