ABSTRACT
Through theoretical calculations and experiments, three operation modes of lateral-field-excited piezoelectric bulk acoustic wave devices, which are referred to as the pure lateral field excitation (LFE), quasi-LFE, and pseudo-LFE modes, are presented. Several 4–6 MHz LFE devices with similar geometry using lithium niobate, lithium tantalate, and AT-cut quartz crystals are fabricated and tested in air and de-ionized water, respectively. The experimental results are in well agreement with the theoretical calculations.

    We report an anomalous electro-optic effect that results in laser scanning along the polarization direction of strontium barium niobate (Sr[sub 0.6]Ba[sub 0.4]Nb[sub 2]O[sub 6], or SBN:60) single crystals under external fields. The origin of such unusual phenomenon is believed to arise from...

    We developed an experimental method for measuring subsecond temporal evolution of the internal field after polarization reversal in ferroelectric crystals, congruent LiNbO[sub 3] and LiTaO[sub 3] crystals. In each crystal the internal field exhibited two distinct relaxations, suggesting that...

    We have discovered an effect of a partially reversible x-ray-induced increase of diffuse x-ray scattering in both congruent and vapor-transport equilibrated single-crystalline lithium niobate and lithium tantalate. The effect has been attributed to x-ray-induced decay of the ferroelectric phase...

    Abstract. Quadrupole electro-optic deflectors were fabricated from 3 mm x 3 mm x 11 mm crystals of lithium-tantalate and lithium-niobate. These devices had a low optical loss and produced linear beam deflections of 6 mrad/kV. The deflectors were used to Q-switch a miniature-diode-pumped...
