【摘要】 Er3+∶Y0.5Gd0.5VO4晶体作为一种新的激光材料,可以用中频感应加热提拉法生长。X射线衍射分析表明,它的结构与Er3+∶GdVO4晶体结构相同,它的晶格常数介于GdVO4和YVO4晶格常数之间。用ICP光谱法测定晶体中Er3+离子分凝系数为1.06;采用稳态纵向热流法测出晶体c轴的热导率为7.2 W.m-1.k-1。更多还原

【Abstract】 New solid-state laser material Er3+∶Y0.5Gd0.5VO4 crystal is grown by a Czochralski method.The X-ray powder diffraction analysis shows that the structure of the prepared crystal is the same as Er3+∶GdVO4.Its lattice parameter is between that of GdVO4 and YVO4 crystal.The segregation coefficient of Er3+ in the crystal is 1.06,measured by ICP.The c directional thermal conductivity is 7.2 W·m-1·K-1(at 298 K).It indicates that Er3+∶Y0.5Gd0.5VO4 crystal can be a candidate of solid-state laser material used in high power LD pumped lasers.更多还原
