摘要
研究了掺Yb3+钇铝石榴石(Yb:YAG)晶体的生长和性能,通过试验得出了合适的温场系统、生长工艺和热处理条件.通过测量Yb:YAG晶体在939nm处的透过率得出了其吸收系数与原始掺杂浓度之间的关系.所生长的Yb:YAG晶体连续输出功率14.1 W,光-光转换效率为38.6%,斜率效率达55.1%.对Yb:YAG-YAG,Nd:YAG-YAG进行了热键合技术研究,获得了较满意的结果.
Abstract
Growth and heat treatment of the yttrium aluminum garnet crystal doped with Yb3+ (Yb:YAG) were studied, and the suitable conditions for its heat field system, growth procedure and annealing conditions were found out dependently. Through the determination of transmission ratio of the crystal at 939 nm wavelength, the relation between the absorb coefficient of the crystal and the initial concentration of Yb in melt is calculated The transition efficiency of optical-to-optical of the crystal is 38.6%, with slope efficiency 55.1%. Heat bonding between Yb:YAG and undoped YAG crystal, and between Νd:YAG and undoped YAG crystal were investigated, and the satisfactory results were attained.
