Annotation: The spectral dependences of optical absorption induced by pulsed radiation with the wavelength of 532 nm in Вi₁₂ТiO₂₀ и Вi₁₂ТiO₂₀: Ca crystals were studied. We obtained from the experiments that the optical absorption of the investigated crystals increases within the spectral range from 500 to 1000 nm and reaches the maximum values at exposures of 500 J/cm²
