Liquid-Phase Exfoliation of Ta<sub>2</sub>NiS<sub>5</sub> and Its Application in Near-Infrared Mode-Locked Fiber Lasers with Evanescent Field Interactions and Passively Q-Switched Bulk Laser
We report on the application of a 1 μm solid-state passively Q-switched (PQS) laser and 1, 1.5 μm mode-locked (ML) fiber lasers based on ternary chalcogenide Ta<sub>2</sub>NiS<sub>5</sub> saturable absorber (SA), which were successfully fabricated by liquid-phase exfoliation...

| description | We report on the application of a 1 μm solid-state passively Q-switched (PQS) laser and 1, 1.5 μm mode-locked (ML) fiber lasers based on ternary chalcogenide Ta<sub>2</sub>NiS<sub>5</sub> saturable absorber (SA), which were successfully fabricated by liquid-phase exfoliation method (LPE). The nonlinear absorption of the Ta<sub>2</sub>NiS<sub>5</sub>-SA was characterized by 0.32 GW/cm<sup>2</sup> and 0.25 GW/cm<sup>2</sup> saturation intensities with 7.3% and 5.1% modulations depths at 1 μm and 1.5 μm, respectively. A PQS solid-state laser operating at 1.0 μm has been realized with the Ta<sub>2</sub>NiS<sub>5</sub>-SA. The maximum average output power, shortest pulse width, pulse energy, and pulse peak power from the PQS laser are 0.257 W, 180 ns, 1.265 μJ, and 7 W. Moreover, highly stable femtosecond laser centered at 1.5 μm, and picosecond centered at 1 μm, ML fiber lasers were obtained using the Ta<sub>2</sub>NiS<sub>5</sub>-SA. A 70 dB signal-to-noise ML laser with a pulse duration of 781 fs was observed in the telecommunication window, which is better than the duration of the previously reported lasers based on Ta<sub>2</sub>NiS<sub>5</sub>. The corresponding maximum single pulse energy and peak power are 0.977 nJ and 1251 W, respectively. The Ta<sub>2</sub>NiS<sub>5</sub>-SA fabricated by the LPE method was applied in near-infrared (NIR) ML fiber lasers (evanescent field interactions) and PQS bulk lasers. The results indicate that Ta<sub>2</sub>NiS<sub>5</sub>-SA prepared by the LPE method can be applied in a 1 μm bulk PQS laser and improved by the new combination mode (evanescent field interactions) for better output performance of the fiber laser. |
