It has been established, for the first time, that the shift of luminescence of Cr3+ ions in forsterite from 900 to 950 nm (FWHM~240 nm) occurs gradually as the Li-codopant concentration is increased. Selectively excited polarized luminescence at 300 and 77 K is used to interpret the nature of the emitting Cr3+ centers. The features of the observed spectra can be explained by replacement of the initial Cr3+ centers by Cr3+-Li associates. The red shift of the Cr3+ luminescence peak and simultaneous reduction of the Cr2+ ions content are shown to be promising for the development of a tunable Cr3+-forsterite laser.
