Absorption measurement is taken in the visible spectral region (650 – 1300 nm). The dopants Cr3+ and Cr4+ ions occupy the tetrahedral sites in the crystal lattice of doped sillenite. The energy level structure of these ions in Bi12SiO20:Cr (BSO:Cr) are presented. The Dq-, B- and C-parameters of the crystal field theory for the Cr3+ and Cr4+ ions were obtained. The spin-coupling energy is also calculated for the chromium ions.
