Abstract

KLN(K₃Li₂Nb₅O₁₅, KLN) and Mn:KLN crystal was grown by Czochralski method. Compared with KLN, the absorption edge of Mn:KLN crystal shifted to infrared band. No correlative property data of KLN was obtained for its weaker photorefractive effect. However, the photorefractive effect of Mn:KLN was enhanced because Mn ²⁺ or Mn⁴⁺ existed in the crystal, which applied more donor and acceptor centers. The two beam coupling coefficient Γ of Mn:KLN crystal with the thickness of 2 mm was up to its maximum value 0.7 cm ^-1 at the external angle of 40°, whereas that of the crystal with the thickness of 0.8 mm was up to its maximum value 1.4 cm^-1 at the external angle of 34°. The response time decreased with the increasing of pump intensity I_P. The response time of Mn:KLN was just several seconds, which was one order of magnitude faster than that of Fe doped LiNbO₃ crystal.
