采用温度梯度法（TGT）生长Yb：Y3Al5O12（Yb：YAG）单晶，在室温下获得了低阈值、高效率的连续激光性能。通过改变输出耦合器的透射率，激光器可以在1030和1049 nm处工作。在10 at. s波长下，1049和1030 nm处的斜率效率分别为57%和68%。% Yb：YAG样品在连续波激光二极管泵浦下进行了研究。泵浦功率对两个波长的激光发射光谱的影响被解决。在不同的激光腔条件下，获得了近衍射极限的光束质量。激光性能的优异表明，热重法生长的Yb：YAG晶体具有良好的光学质量，在高功率固体激光器中具有潜在的应用前景。
Low-threshold and highly efficient continuous-wave laser performance of Yb:Y3Al5O12 (Yb:YAG) single crystal grown by a temperature gradient technique (TGT) was achieved at room temperature. The laser can be operated at 1030 and 1049 nm by varying the transmission of the output coupler. Slope efficiencies of 57% and 68% at 1049 and 1030 nm, respectively, were achieved for 10 at. % Yb:YAG sample in continuous-wave laser-diode pumping. The effect of pump power on the laser emission spectrum of both wavelengths is addressed. The near-diffraction-limited beam quality for different laser cavities was achieved. The excellent laser performance indicates that TGT-grown Yb:YAG crystals have very good optical quality and can be potentially used in high-power solid-state lasers.
