Abstract

Using the planar optical waveguide geometry, a CARS spectrum of a 25 A film of TiO₂ on a Nb205 waveguide has been observed. Spectra of monolayers of phenol and pyridine adsorbed on ZnO surfaces also have been observed under high vacuum conditions. When most of the CARS contribution from a waveguide is eliminated by an interference condition, submonolayer quantities are detectable.
