Using the tightly focused visible light (wavelength λ=488nm) illuminating, the ferroelectric domain patterns of the undoped lithium niobate crystal have been demonstrated. The influence of the visible light intensity on the domain nucleation field was investigated. The reduction of nucleation field decreases exponentially with increasing incident irradiation intensity. Once a domain is nucleated it can be dictated by the far-field light diffraction patterns. An assumption is proposed that the reduction of nucleation field is directly related to the defects mobility and structure of the crystals.

Smoothing Procedure

A procedure is described for estimating the background outline in powder diffraction patterns. It essentially consists of an extension of traditional smoothing procedures to include Bragg peaks in addition to profile random fluctuations. This approach is particularly suited for dealing with diffraction patterns obtained from semicrystalline polymer samples; some applications to this kind of experimental data are presented.
