我们在实验上证明了在9字锁模光纤激光器中直接产生高能量耗散孤子共振(DSR)和矩形类噪声脉冲(NLP)。脉冲宽度可调至144.6 ns，平均输出功率可调至100.25 mW至677.5 mW。在泵浦功率为6.7W时，脉冲能量的最大值为713.2 nJ，据我们所知，这是在2μm范围内的最高能量。此外，还得到了脉冲束能量为452nJ的矩形NLP。
We experimentally demonstrate a direct generation of high-energy dissipative soliton resonance (DSR) and rectangular noise-like pulse (NLP) in a figure-9 thulium-holmium-doped mode-locked fiber laser. The pulse duration and average output power of the DSR can be tuned from 33.5 ns to 144.6 ns, and from 100.25 mW to 677.5 mW, respectively. The maximum of pulse energy is 713.2 nJ without wave breaking at pump power of 6.7 W, which is the highest energy of DSR in the region of 2 μm, to the best of our knowledge. In addition, the rectangular NLP with 452 nJ pulse bunch energy is also obtained.
