【 摘 要 】

The high- and low- frequency electro-optic coefficients r222of In-doped lithium niobate (LN) and the corresponding dielectric permittivity as well, have been experimentally determined and compared with the results obtained in undoped congruent LN crystals. Compared to pure congruent lithium niobate, a low acoustic contribution of the electro-optic and dielectric properties are originally found in indium (In)-doped congruent lithium niobate (LN:In) crystals in the low indium concentration range [0.12-1.7 mol%]. All reported results confirm that the LN:In is a very promising candidate for several non-linear devices as Pockels cells for laser Q-switching.
