【摘要】 报道了以掺Yb介质硅酸镥钇晶体为增益介质的激光行为。在自由运转的条件下,在1086 nm的中心波长处用2.5%的输出耦合镜得到7.8 W的连续激光输出,相应的斜效率为64%。利用SF14棱镜作为腔内调谐元件,激光输出的调谐范围为1014~1091 nm。更多还原

【Abstract】 We demonstrate continuous-wave laser action in a Yb³+-doped lutetium Yttrium oxyorthosilicate（Yb_xLu_yY₁-x-y）₂SiO₅（Yb...LYSO） crystal（0.001≤x≤0.5,0≤y≤0.8）.In the free-running operation,we obtained an output power as high as 7.8 W centered about 1086 nm for a 2.5% output coupler,corresponding to a slope efficiency of 64%.Using a SF14 prism as an intracavity tuning element,the tunability of the Yb...LYSO laser in the spectral range of 1014¹091 nm has been achieved.更多还原
