Optical homogeneity and photorefractive properties of stoichiometric and congruent lithium niobate crystals grown using charges of different origins

A stoichiometric lithium niobate crystal (LiNbO 3 st ) and congruent lithium niobate crystals grown from a charge prepared using cyclohexanone as an extractant (LiNbO 3 cong (CHN)) and a charge prepared using cyclohexanone and carboxylic acid dimethylamides as extractants (LiNbO 3 cong (CHN + A)) ha...

Zusammenfassung:A stoichiometric lithium niobate crystal (LiNbO 3 st ) and congruent lithium niobate crystals grown from a charge prepared using cyclohexanone as an extractant (LiNbO 3 cong (CHN)) and a charge prepared using cyclohexanone and carboxylic acid dimethylamides as extractants (LiNbO 3 cong (CHN + A)) have been characterized by photoinduced light scattering and laser conoscopy. The results demonstrate that the LiNbO 3 cong (CHN + A) crystals are rather homogeneous along their growth direction and possess good optical properties, similar to those of the LiNbO 3 cong (CHN) crystal. At the same time, the LiNbO 3 cong (CHN + A) crystal offers significantly better electro-optical properties ( r e = 29.3 pm/V).
