摘要：
Kinetics of bulk screening of depolarization field was studied in single crystalline lithium niobate and lithium tantalate of various compositions by analysis of the switching current, birefringence contrast, and diffraction of coherent light on the domain walls. The bulk screening process was quantitatively characterized by several essential parameters, such as a type of relaxation law, relaxation time constants, and maximum value of bulk screening field. Advantages and disadvantages of used experimental methods were discussed. The comparison of the obtained and previously published results was carried out.
