D. Xue et al., Chemical bond analysis of the second-order nonlinear optical behaviour of Mg-doped lithium niobate, J PHYS-COND, 12(28), 2000, pp. 6245-6252
Second-order nonlinear optical properties of Mg-doped lithium niobate singl
e crystals are quantitatively studied from the chemical bond viewpoint. The
results show that the second-order nonlinear optical response of Mg-doped
LiNbO3 single crystals at 1079 nm decreases linearly with increasing Mg con
centration in the crystal. This linear correlation is quantitatively evalua
ted in the current work.
