Abstract

Co-doping photo-refractive sensitive dopants CeO₂, CuO and Fe₂O₃, Ce:Cu:Fe:LiNbO₃ crystals were grown by Czochralski technique for the first time. The absorption spectra of the crystals were measured. The absorption edges of Cu:LiNbO₃, Fe:LiNbO₃ and Ce:Cu:Fe:LiNbO₃ crystals shifted to red compared with LiNbO₃ crystal and the absorption edge of Ce:Cu:Fe:LiNbO₃ crystal shifted to red compared with Cu:LiNbO₃ and Fe:LiNbO₃ crystals. The exponential gain coefficients of Ce:Cu:Fe:LiNbO₃ crystals with different thickness (0.2 mm, 0.4 mm, 1.0 mm and 2.0 mm) were measured. The exponential gain coefficient of thin crystal sample increased. The mechanism of the enhancement of the exponential gain coefficient of thin crystal was investigated.
