We have demonstrated the continuous wave and passively Q-switched Tm, Mg: LiTaO3 lasers for the first time. In continuous wave (CW) regime, a maximum CW output power of 1.03 W at 1952 nm was obtained, giving a slope efficiency of 9.5% and a beam quality M2 = 2.2. In passive Q-switching regime, a single walled carbon nanotube (SWCNT) was employed as saturable absorber (SA). The Tm,Mg:LiTaO3 laser has yielded a pulse of 560 ns under repetition rate of 34.2 kHz at 1926 nm, corresponding to a single pulse energy of 10.1 μJ. The results indicate a promising potential of nonlinear crystals in the applications for laser host materials.
我们首次展示了连续波和被动调Q的Tm，Mg：LiTaO3激光器。在连续波（CW）模式下，在1952nm处获得了1.03W的最大连续波输出功率，斜率效率为9.5%，光束质量M2 = 2.2。在被动调Q模式下，使用单壁碳纳米管（SWCNT）作为可饱和吸收体（SA）。Tm，Mg：LiTaO3激光器在1926nm、34.2kHz的重复频率下产生了560ns的脉冲，对应单脉冲能量为10.1μJ。结果表明非线性晶体在激光基质材料应用中具有广阔的潜力。
