Characteristics of diode-wing-pumped highly efficient Tm:LuAG lasers running both in continuous wave (CW) and electro-optical Q-switching regimes have been investigated. Using a simple plane-plane cavity, a maximum CW output power of 8.5 W has been achieved with a corresponding slope efficiency of 44.5% by "wing pumping" at 790 nm. With a V-shaped cavity, a diode-wing-pumped MgO:LiNbO crystal based electro-optically Q-switched Tm:LuAG laser at 2022.9 nm delivered a maximum pulse energy of 10.8 mJ and a minimum pulse width of 52 ns at a corresponding repetition rate of 100 Hz. To the best of our knowledge, the achieved CW output power and Q-switched pulse energy have both set records for all-solid-state Tm:LuAG lasers, which well reveals an efficient way to generate high-power and high-energy lasers at 2 μm wavelength.
研究了在连续波（CW）和电光调Q模式下运行的二极管翼泵浦高效Tm:LuAG激光器的特性。使用简单的平-平腔，通过790nm的“翼泵浦”实现了8.5W的最大连续波输出功率，相应的斜率效率为44.5%。采用V形腔，基于二极管翼泵浦MgO:LiNbO晶体的电光调Q Tm:LuAG激光器在2022.9nm处，在100Hz的相应重复频率下，最大脉冲能量为10.8mJ，最小脉冲宽度为52ns。据我们所知，所实现的连续波输出功率和调Q脉冲能量均为全固态Tm:LuAG激光器创下了记录，这很好地揭示了一种在2μm波长产生高功率和高能量激光器的有效方法。
