Abstract :
A method for achieving the ultrahigh sensitivity required for surface vibrational spectroscopy is proposed. Polarization selective heterodyne detection permits shot-noise limited submonolayer detection with classically noisy picosecond laser sources. Furthermore, the polarization selectivity is used to eliminate the overwhelming thermally induced changes in surface reflecfivity.
