Abstract
Barium titanate is important as a nonlinear optical material primarily because of its large photorefractive gain. This gain is large enough to give rise to self-pumped phase conjugation at low optical power 1 Several studies have been conducted on enhancing the gain of the crystal through controlled doping2-5 and annealing.3,6,7 These dopants have, till now, been confined to transition metals such as iron,2,3 chromium,4 iron + nickel,5 and cobalt.5 In this talk, we report preliminary results of the self-pumped phase conjugate reflectivity in cerium doped barium titanate.
