Near-field optical microscopy (NSOM) is a technique that offers several advantages over conventional optical microscopy. We present evidence for a z-polarization component and a surface-enhancement effect in near-field Raman data. Observation of Raman scattering from the fiber probe and Rayleigh scattering may be used to determine probe quality. The sample studied is KTiOPO/sub 4/ (KTP) a nonlinear optical material, for which a comparison of near-field and far-field spectra is shown.
