Abstract

Photoinduced open-circuit pyroelectric and saturated photovoltaic fields of ~200 and ~10 V/cm, respectively, have been measured in a self-pumped phase-conjugating (PC) BaTiO3 crystal. Saturated photovoltaic field, photoresistivity, and grating erasure measurements gave a value for the photoconductivity σp ~ 10−10 I and a dark conductivity σd = 1.5 × 10−12 (Ω-cm)−1. Frequency shifts of the PC beam of a few hertz were only observed when the emission was spontaneously pulsating and not in a steady state.
