The polarisation absorption spectra of forsterite single crystals grown from a melt containing from 0.015 to 0.97 wt% of chromium are studied. Most of the crystals were grown by the Czochralski method under standard oxidation conditions (1.4-2.4 vol % of oxygen). Some crystals were grown in the atmosphere with a higher content of oxygen ({approx}12 vol %) or in the neutral atmosphere (100% of Ar). Crystals grown from a melt containing more than 0.6 wt % of chromium exhibited the saturation of absorption of Cr{sup 4+} ions. The maximum absorption coefficient of Cr{sup 4+} ions at 1064 nm was {approx}3.2 cm{sup -1}. The relative content of Cr{sup 3+} ions also increased (approximately by 70% in the range studied) with increasing the doping level. The relative content of Cr{sup 3+} ions in a crystal grown in the atmosphere with a high content of oxygen ({approx}12 vol %) was approximately lower by a factor of 1.5 than that in a crystal grown in the standard oxidation atmosphere.
