Abstract By measuring Raman scattering spectra of KTiOPO4(KTP) crystal with several configurations, we found the orientation of polarizability tensor in flux-grown KTP (KTPF) was perpendicular to the orientation of polarizability tensor in hydrothermally grown KTP (KTPH). Fluorescent and Raman spectra of KTP were measured from room temperature to 4.2K. The appearance of peaks at 135cm-1 and 800cm-1 at 77K and the temperature dependence of Raman spectrum lines are discussed.
