摘要：
Pure and Cr2O3-doped Bi12SiO20 (BSO) single crystals have been successfully grown using Czochralski technique. Doping 30 ppm of Cr2O3 into BSO single crystals has lowered the transmittance and increased the photochromic effect of the materials significantly. Although the overall diffraction efficiency of photorefractive effect in response to 633 nm laser beam has not been increased, the intrinsic diffraction efficiency (eta(i)) and the response time constant (tau) have been improved markedly. The applicability of the BSO crystals in the red light regime is thus increased.
