Abstract
Confocal Raman spectroscopy is applied to identify ferroelectric domain structure sensitive
phonon modes in potassium titanyl phosphate. Therefore, polarization-dependent measurements in
various scattering configurations have been performed to characterize the fundamental Raman
spectra of the material. The obtained spectra are discussed qualitatively based on an internal mode
assignment. In the main part of this work, we have characterized z-cut periodically poled potassium
titanyl phosphate in terms of polarity- and structure-sensitive phonon modes. Here, we find vibrations
whose intensities are linked to the ferroelectric domain walls. We interpret this in terms of
changes in the polarizability originating from strain induced by domain boundaries and the inner
field distribution. Hence, a direct and 3D visualization of ferroelectric domain structures becomes
possible in potassium titanyl phosphate.
