“…Here, the local inversion of domains is based on an induced pyroelectric or thermoelectric field. [14][15][16][17][18][19][20] However, the domain length is restricted in both cases to a few hundred nanometers due to the strong absorption in this wavelength regime.…”

We explore a physical approach to invert ferroelectric domains in the volume of MgO-doped lithium niobate crystals without any external electric field. Permanent defect structures are created by focused infrared femtosecond laser pulses below the material surface along the polar axis followed by a thermal treatment. This procedure leads to an inversion of ferroelectric domains beneath and above the laser-induced filaments up to the surfaces of the crystal. All domain walls are straight and up to 800 μm long. We measure the domain width in dependence on the length of the filaments and the writing energy. The smallest achieved domain width and the domain spacing is 1 μm. We propose a model taking into account the temperature dependence of the pyroelectric field and thermally activated bulk charges to explain the mechanism of domain inversion. Our findings pave the way to all-optical printing of arbitrary ferroelectric domain structures for nonlinear photonic applications.

“…17 In contrast, the irradiation by infrared laser (wavelength 10.6 lm) with pulse duration in millisecond range initiates the formation of the bulk domain structure consisting of nanoscale domain rays with depth up to 200 lm. 20,23,26 In this work, we report the study of the polarization reversal as a result of heating-cooling cycles in congruent MgO doped LN (MgO:LN). The change of the sizes of isolated domains produced by local field applied using conductive SPM tip has been measured by piezoelectric force microscopy (PFM).…”

Polarization reversal during heating-cooling cycles was investigated in MgO doped lithium niobate (MgO:LN) crystal using piezoresponse force microscopy. The essential dependence of the domain structure evolution scenario on the maximal temperature in the cycle has been revealed experimentally. It has been shown that the heating of the engineered domain matrix from room temperature to 85 C leads to light size reduction of the isolated domains at the matrix edges, whereas the heating to 170 C leads to essential reduction of the domain size. The opposite strong effect of the domain formation and growth during cooling after pulse heating have been revealed in single domain MgO:LN. The simulation of the time dependence of the pyroelectric field during heating-cooling cycle allowed to reveal the temperature hysteresis and to explain all observed effects taking into account the temperature dependence of the bulk conductivity.

“…Especially bulk screening effects have to be considered, which are a result of the increased conductivity and the pyroelectric effect. 17,18 Also, the diffuse phase transition and the formation of domain structures in relaxors (SBN) are quite different from normal ferroelectric crystals (LiNbO 3 ), which can further influence the domain inversion process. Full understanding of the domain inversion process by UV laser direct writing not only in SBN, but also in LiNbO 3 , does certainly require further investigations.…”

We report ferroelectric domain inversion in strontium barium niobate (SBN) single crystals by irradiating the surface locally with a strongly focused ultraviolet (UV) laser beam. The generated domains are investigated using piezoresponse force microscopy. We propose a simple model that allows predicting the domain width as a function of the irradiation intensity, which indeed applies for both SBN and LiNbO 3. Evidently, though fundamentally different, the domain structure of both SBN and LiNbO 3 can be engineered through similar UV irradiation. V
