Ionic conductivity and its effect on the optical properties of LBO crystals

Temperature dependence of the dielectric losses conditioned by the ionic conductivity (IC) of nonlinear optical lithium triborate (LBO) crystals was investigated both theoretically and experimentally, exploiting the variation of the line form of LBO piezoelectric resonances with temperature. An effect of the IC on the optical properties of LBO crystals was considered. The relation between the LBO IC and its resistance to UV radiation was investigated.
