Abstract

Doping MnO in LiNbO₃ crystal, Mn:LiNbO₃ crystals of different ratio of Li/Nb = 0.94, 1.00, 1.20, 1.44 have been grown. The crystal of Li/Nb = 1.44 is near chemical metric ratio Mn:LiNbO₃ crystal. Absorption spectra of Mn:LiNbO₃ crystal were measured. Its original absorption edge shifted to red compared with LiNbO₃ crystal. The original edges of Mn:LiNbO₃ crystals of ratio Li/Nb = 1.00, 1.20, 1.44 shifted to violet compared with Mn:LiNbO₃ crystal of ratio Li/Nb = 0.94. When the ratio of Li/Nb increased, the exponential gain coefficient increased and the response time decreased. The exponential gain coefficient (formula available in paper).
