Sc:Ce:LiTaO3 crystals
were grown by using the Czochralski method. The two-wave coupling experiments
and transmitted facula distortion method were used to measuring the
photorefractive properties and the optical damage resistance, respectively. It
was found that the photorefractive response speed of Sc:Ce:LiTaO3 was four times
faster than that of Ce:LiTaO3 and
the resistance ability to optical damage was two orders higher than that of
Ce:LiTaO3.
It could be attributed to the Ce ions losing their electron acceptor
properties, which result in the increase of photoconductivity. In this paper,
site occupation mechanism of impurities was also discussed to explain the
increased of photoconductivity.
