We report on a generation of self-starting mode-locked resembling (MLR) pulses in an all-fiber, gain-switched Tm(3+)-doped fiber laser operating at 2 μm wavelength, which we believe to be the first demonstration of such an approach. The laser delivers 100% modulated MLR pulses within an envelope of ~30 ns gain-switched pulse at a repetition rate of 30 kHz. The maximum average output power is 0.4 W and the maximum peak-power of MLR pulses can be as high as 1.1 kW. The performance of the laser is described.
我们报道了一种在工作于 2 µm 波长的全光纤、增益开关掺铥光纤激光器中产生的自启动类似锁模（MLR）脉冲，我们相信这是这种方法的首次演示。该激光器在 30 kHz 的重复率下，在约 30 ns 的增益开关脉冲包络内产生 100%调制的 MLR 脉冲。最大平均输出功率为 0.4 W，MLR 脉冲的最大峰值功率可达 1.1 kW。我们描述了该激光器的性能。
