Abstract :
Chromium-doped forsterite single crystals (Cr:Mg2SiO4) are an active medium for solid-state lasers tunable near-IR region with use of Cr4+ and Cr3+ ions as active centers. The influence of high-energy electrons irradiation on absorption and luminescence spectra of Cr3+- and Cr4+-ions in forsterite laser crystals has been studied for the first time. The crystals were irradiated by 21 MeV electrons with fluence varied within the range 7·1013/2·1015 cm-2. Gamma irradiation of the crystals with 1 MeV energy and a dose up to 3·105 Gy had also been performed.
