Direct-writing of inverted domains in lithium niobate using a continuous wave ultra violet laser

Direct-writing of inverted domains in lithium niobate using a continuous wave ultra violet laser
Direct-writing of inverted domains in lithium niobate using a continuous wave ultra violet laser
The inversion of ferroelectric domains in lithium niobate by a scanning focused ultra-violet laser beam (lambda = 244nm) is demonstrated. The resulting domain patterns are interrogated using piezoresponse force microscopy and by chemical etching in hydrofluoric acid. Direct ultra-violet laser poling was observed in un-doped congruent, iron doped congruent and titanium in-diffused congruent lithium niobate single crystals. A model is proposed to explain the mechanism of domain inversion.

Abstract

The inversion of ferroelectric domains in lithium niobate by a scanning focused ultra-violet laser beam (lambda = 244nm) is demonstrated. The resulting domain patterns are interrogated using piezoresponse force microscopy and by chemical etching in hydrofluoric acid. Direct ultra-violet laser poling was observed in un-doped congruent, iron doped congruent and titanium in-diffused congruent lithium niobate single crystals. A model is proposed to explain the mechanism of domain inversion.
