在1.93-2.00 /spl μ/m范围内观察到Tm：YALO的激光发射。一个模型，包括再吸收损耗和偏振效应，预测输出波长作为激光器参数的函数，被用来设计一个Tm：YALO激光器的输出限制为1.94 /spl μ/m，而不采用调谐元件。该激光器在液态水中具有1.94 /spl mu/m的强吸收系数（是2.02-/spl mu/m Tm：YAG激光器的两倍，是2.09-/spl mu/m Ho：YAG激光器的四倍），可用于医疗应用。>
Laser emission from Tm:YALO is observed over the range 1.93-2.00 /spl mu/m. A model including reabsorption loss and polarization effects, predicting the output wavelength as a function of laser parameters, is used to design a Tm:YALO laser with output restricted to 1.94 /spl mu/m, without employing a tuning element. This laser is potentially useful for medical applications, offing to the strong absorption coefficient at 1.94 /spl mu/m in liquid water (twice that of the 2.02-/spl mu/m Tm:YAG laser and four times that of the 2.09-/spl mu/m Ho:YAG laser). >
