本文报道了Cr ~（3+）：CaMgSi_2 O_6（Cr ~（3+）：CMS）晶体的生长和光谱性质。采用提拉法生长了Cr ~（3+）：CMS晶体。光谱性质的研究表明，Cr ~（3+）：CMS晶体具有宽而强的吸收和发射截面。它有两个宽的吸收带，中心在460 nm和652 nm。在300 K时，986.1 nm处的发射截面σe为14.39 × 10−20 cm 2。发射半高宽达到212 nm。因此，Cr ~（3+）：CMS晶体是一种很有潜力的可调谐超短脉冲激光晶体。
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.
