Abstract

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.
