Abstract
Using tightly focused laser beams, features of space charge fields (∼107 V/m) are studied through the photoionization of doped Jahn–Teller Fe2+ ions in LiNbO3 single crystals. These fields can be used for selective formation of the inverse domain state following the additional application of a field with a strength below the coercive field. The characteristics of laser-induced domains and periodic domain structures are studied by laser-acoustic means.
