本文报道了Yb（3+）在非中心对称的RbTiOPO（4）晶体中的三种偏振态的连续激光发射。当吸收功率为386 mW时，在1050 nm处获得了154 mW的最大输出功率。最高斜率效率达到约60%，最低阈值（相对于吸收功率）为18 mW。激光波长可调谐范围为1009 ~ 1081 nm。
We report on continuous-wave lasing of Yb(3+) at room temperature in the noncentrosymmetric RbTiOPO(4) crystal, codoped with Nb(5+), for all three possible polarizations. A maximum output power of 154 mW at 1050 nm was obtained for an absorbed power of 386 mW. The highest slope efficiency reached approximately 60% and the lowest threshold (with respect to the absorbed power) was 18 mW. The laser was tunable from 1009 to 1081 nm.
