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 doping^2-5 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.
