摘要

我们提出并演示了一种新的调q掺铥光纤激光器(TDFL)，该激光器利用基于钼铝硼化体(MoAlB)的无源饱和吸收体(SA)。MoAlB是一种金属-陶瓷基材料;它嵌入在聚乙烯醇(PVA)材料中，作为SA运行。激光器成功地产生了稳定的调q脉冲，工作波长为1974.7 nm，最大重复频率为57.7 kHz，最小脉冲宽度为1.79 μs。在436 mW泵功率下，最大脉冲能量为90.2 nJ。我们的实验首次展示了在2 μm波长区域使用MoAlB产生脉冲激光。

Q-Switched Thulium-Doped Fiber Laser with Molybdenum–Aluminum-Boride-Based Saturable Absorber

We propose and demonstrate a new Q-switched thulium-doped fiber laser (TDFL) by utilizing a passive saturable absorber (SA) based on Molybdenum–Aluminium boride (MoAlB). The MoAlB is a metal–ceramic-based material; it is embedded in polyvinyl-alcohol (PVA) material to operate as the SA. The laser successfully generates stable Q-switched pulses operating at 1974.7 nm with a maximum repetition rate of 57.7 kHz and a minimum pulse width of 1.79 μs. A maximum pulse energy of 90.2 nJ is recorded at 436 mW pump power. Our experiment is the first demonstration on the use of MoAlB for the pulse laser generation in the 2 μm wavelength region.
