  • High-energy dissipative soliton resonance and rectangular noise-like pulse in a figure-9 Tm fiber laser

    摘要： 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.

  • Dual-wavelength thulium/holmium-doped fiber laser generation in 2 <i>μ</i> m region with high side-mode suppression ratio

    摘要： We demonstrate a dual-wavelength laser with emission in the 2 μm wavelength region using a thulium/holmium co-doped fiber and a non-adiabatic tapered fiber as a comb filter. The configuration employed a backward pumping scheme and dual-wavelength laser was generated at 2023.53 and 2032.82 nm. The side-mode suppression ratio (SMSR) is more than 44 dB with overall good stability performance. The proposed configuration presents a simple yet practical scheme of generating 2 μm dual-wavelength laser with good SMSR. This investigation may offer a more efficient yet eye safe dual-wavelength related applications for end users.
