采用直拉法成功获得了 4-at.% Tm:Sc2SiO5 (Tm:SSO) 晶体。研究了晶体的光学性质和热导率。在激光二极管（LD）泵浦下实现了尺寸为3 mm×3 mm×3 mm的（100）切割Tm:SSO的宽连续波（CW）激光输出。激光发射的半峰全宽（FWHM）达到21 nm。 Tm:SSO 的激光阈值为 0.43 W。Tm:SSO 的高效二极管泵浦 CW 激光器性能被证明具有 25.9% 的斜率效率和 934 mW 的最大输出功率。
The 4-at.% Tm:Sc2SiO5 (Tm:SSO) crystal is successfully obtained by the Czochralski method. The optical properties and thermal conductivity of the crystal are investigated. The broad continuous wave (CW) laser output of (100)-cut Tm:SSO with the dimensions of 3 mm× 3 mm× 3 mm under laser diode (LD)-pumping is realized. The full width at half maximum (FWHM) of the laser emitting reaches up to 21 nm. The laser threshold of Tm:SSO is measured to be 0.43 W. Efficient diode-pumped CW laser performance of Tm:SSO is demonstrated with a slope efficiency of 25.9% and maximum output power of 934 mW.
