Paper 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.
