Abstract
This letter reports the two-wave mixing experimental results of tetragonal Fe-doped KTa1−xNbxO3. A 7.3 cm−1 gain coefficient and 42% diffraction efficiency have been obtained. For the first time internally self-pumped phase conjugation is being observed in this crystal. At room temperature, the conjugate reflectivity measured is 21%.Keywords
