Elektrooptische und elektrostriktive Eigenschaften von Bleitetraborat PbB4O7

Abstract

Abstract The linear electrooptical tensor [rijk ] and the tensor of the adiabatic linear electrostriction [dijk S ] of lead tetraborate (PbB4O7, point group mm2) have been determined: r 113 = +2.35(8), r 223 = +2.40(8), r 333 = +2.83(9), r 131 = +2.39(7), r 232 = +0.95(7); d311 S = +2.8(2), d322 S = +2.6(2), d333 S = ±0.0(1), d113 S = +2.1(1), d223 S = +1.7(2) (Unit: 10−12 m/V, T = 295 K, λ = 633 nm).
