We report photovoltaic constant and photoconductivity of Ce,Mn:LiNbO 3 crystals. Using the DC electric field dependence of non-phase-matched second-harmonic generation, photovoltaic constant and photoconductivity were deduced from an analysis of the observed relaxation behavior of space-charge field at two different light intensities for photorefraction. In Ce,Mn:LiNbO 3 crystal, the...
We report a simple method for determining photovoltaic constant and conductivity of any photorefractive crystals which have no inversion symmetry by utilizing the electric field dependence of non-phase-matched second harmonic generation. The photovoltaic constant, dark conductivity and photoconductivity are easily deduced from an analysis of the observed relaxation behavior of space-charge field at...
