Cr³⁺-doped CaMgSi₂O₆crystal: a promising tunable laser and ultrashort laser crystal

Abstract

This paper reports the growth and spectral properties of the Cr3+:CaMgSi2O6 (Cr3+:CMS) crystal. The Cr3+:CMS crystal was grown by the Czochralski method. Investigation of its spectral properties shows that the Cr3+:CMS crystal has broad, strong absorption and emission cross-sections. It has two broad absorption bands which center at 460 nm and 652 nm. The emission cross-section σe at 986.1 nm is 14.39 × 10−20 cm2 at 300 K. The emission FWHM is up to 212 nm. Therefore, the Cr3+:CMS crystal can be considered as a potential tunable and ultrashort pulse laser crystal.
