We present the first successful combination of the revolutionary techniques of SERS and femtosecond stimulated Raman spectroscopy (FSRS), demonstrating surface enhanced-FSRS (SE-FSRS). Using a picosecond Raman and femtosecond probe pulse, we obtain highly resolved stimulated Raman spectra with an enhancement factor of 104 � 106, now enabling structural probing of ultrafast reaction dynamics with the signal enhancement of SERS.   We also discuss our efforts towards monitoring ultrafast structural dynamics of molecules adsorbed to metal surfaces using three-pulse time-resolved SE-FSRS.
