Abstract
The linear bulk photovoltaic effect (BPE) and photorefractive effect (PR) in La3Ga5SiO14 has interesting peculiarities, connected with symmetry of the crystal. Due to the symmetry the both effects depend on the light polarization. The symmetry permits also to observe the circular BPE. The all these effects have extrinsic character and depend on the impurity ions. In the present paper we investigated the linear and circular BPE for different impurities.
