Abstract
We describe theory and experiment for Fourier-transform sum-frequency surface vibrational spectroscopy using femtosecond lasers and discuss some practical issues in comparing it with the multichannel dispersive sum-frequency generation approach to obtain sub-laser-linewidth resolution in vibrational spectra. A signal-to-noise ratio analysis shows that the former is inferior for several inherent reasons if infrared and visible pulses used are derived from a typical 1 kHz femtosecond oscillator–amplifier system.
