dc.description.abstractA method is presented to perform direct photoconductivity measurements of Sr0.61Ba0.39Nb2O6:Ce crystals at high intensities: A high voltage is applied to the sample and subsequent illumination yields a photocurrent through the crystal which charges a capacitor. Finally an electrometer measures the voltage of this capacitor. From voltage, capacity and exposure time the photoconductivity is calculated. Measurements with light pulses of a Q-switched frequency-doubled Nd:YAG laser (pulse duration 20 ns, light wavelength 532 nm) are performed. The photoconductivity sigma(ph) increases sublinearly with light intensity I according to sigma(ph) proportional to I-x with x<1. The experimental results point to Ce-3+/4+ as the dominant photorefractive center in Sr0.61Ba0.39Nb2O6:Ce at high intensities. (C) 1996 American Institute of Physics.pt
