Abstract
We report the first observation of self-pumping1 in Ba.5Sr1.5K.25Na.75Nb5O15 (BSKNN-III) and Sr.6Ba.4Nb2O6 (SBN) with Cerium in 9-fold coordinate sites. Phase-conjugate reflectivities on the order of 20% have been observed from both crystals along with relatively fast response times. The observations reported here were carried out at laser wavelengths of 647 nm and 676 nm.
