We report on experimental results showing a strong wavelength-dependence of cross-talk between photorefractive gratings simultaneously recorded in Bi12SiO20 crystals in the diffusion regime. We find unusually high cross-talk for two gratings with close spatial frequencies at wavelengths 488 and 476 nm. The results indicate that the density of free charge carriers does not directly follow light modulation at low spatial frequencies.
