报道了一种新的掺Yb ~（3+）LuAlO_3晶体（Yb：LuAP）的晶体生长、偏振光谱特性、寿命测量和二极管泵浦下的连续激光性能。在978.5 nm处测得E//c偏振的最大吸收截面为6.6·10-20 cm 2。测量了LuAP中Yb ~（3+）离子F5/22簇的辐射寿命为475 μs。连续激光器的行动表明，输出功率高达9.6 W和斜率效率高达84.5%。对于E//c偏振，证明了82 nm的可调谐范围。
Crystal growth, polarized spectroscopic properties, lifetime measurements, and CW laser performance under diode pumping of a new Yb3+-doped LuAlO3 crystal (Yb:LuAP) are reported for the first time, to the best of our knowledge. The maximum absorption cross section of 6.6·10-20 cm2 at 978.5 nm was determined for E//c polarization. The radiative lifetime of F5/22 manifold of Yb3+ ions in LuAP was measured to be 475 μs. CW laser action was demonstrated with output powers up to 9.6 W and slope efficiencies up to 84.5%. 82 nm tunability range was demonstrated for E//c polarization.
