Abstract

Grey tracks produced in $KTiOPO_4$ (KTP) by applying a dc electric field have been studied through optical absorption, Raman scattering, and synchrotron x-ray topography. A study of the optical absorption and Raman scattering from the grey-tracked region suggests that their formation is accompanied by changes in the electronic levels of $Ti^{4+}$. There is no evidence for a major structural change or disorder in the grey-tracked region. However, the x-ray topographs do indicate the presence of a remnant strain in the lattice, which might contribute to the observed changes in the Raman intensities.
