Abstract
Pure and Cr-doped single crystals KTP which are grown by the TSSG meth od are large and good quality ones. Brillouin scattering experiment is carried out to study the elastic properties of the grown crystal. We obtain all of nine elastic constants of the KTP crystal from one cubic sample, through which piezoelectric effect is considered. As a result the obtained elastic constants are some what different from the other s' results. In this work we use the back scattering method for determi ning elastic constants of our samples.
