摘要: 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 first time internally self‐pumped phase conjugation is being observed in this crystal. At room temperature, conjugate reflectivity measured 21%.
