报道了首次利用黑磷（BP）/SnSe 2异质结作为可饱和吸收体（SA）实现掺铒光纤激光器的调Q操作。采用液相合成法制备了BP/SnSe_2异质结，并对其特性进行了观察。基于BP/SnSe 2 SA实现了稳定的Q开关操作。最大峰值功率为71.27 mW，最小脉冲宽度为910 ns。本文首次演示了BP/SnSe 2异质结SA在中红外波段的脉冲调制特性，为基于BP和二维过渡金属二硫属化物的异质结的应用奠定了重要基础。
In this paper, we report the first Q‐switching operation utilizing black phosphorus (BP)/SnSe2 heterojunction as the saturable absorber (SA) in an Er‐doped fiber laser. The BP/SnSe2 heterojunction was prepared by the liquid phase combination method and its properties were observed. Stable Q‐switching operations were achieved based on the BP/SnSe2 SA. The maximum peak power of 71.27 mW and the minimum pulse width of 910 ns were produced, respectively. This paper demonstrates the pulse modulation characteristics of BP/SnSe2 heterojunction SA in the midinfrared region for the first time, laying an important foundation for the application of heterojunction based on BP and two‐dimensional transition metal dichalcogenides.
