摘要
使用提拉法成功生长出了尺寸为25 mm×50 mm的5at%Yb∶GdTaO4晶体。通过X射线衍射确定了晶体的结构,并拟合得到了晶体的结构参数,分析了GdTaO4晶体容易产生解理和开裂的原因。测量了它的吸收光谱以及低温和常温的光致发光光谱,计算得到了5at%Yb∶GdTaO4晶体吸收截面和受激发射截面,并综合评估了晶体的激光性能。结果表明:5at%Yb∶GdTaO4晶体是非常有希望实现全固态超短脉冲的工作物质。
GdTaO4 crystals doped with 5at% Yb3+ was grown by Cz method successfully.The structure was determined by X-ray diffraction and the structure parameters were obtained by further Retiveld refinement.The origin of cleavage and cracks was discussed.The absorption spectrum as well as low-temperature and room-temperature emission spectra was recorded.The absorption cross section and simulated emission cross section were calculated and the laser properties were also evaluated.The results predicted that it was a potential solid-state laser media for ultra-short-pulse laser applications.
