Abstract

In this article, NiS₂ SA was investigated and played a key role in a 2.8 μm fiber laser to achieve typical Q-switched pulse. The 7 mol.% double-cladding Er³⁺-doped ZBLAN fiber with 2.8 m long was used to generated the laser with the center wavelength of 2789.2 nm, the NiS₂ SA provided the optical nonlinearity and pulse-shaped capacity to achieve a pulse duration of 423 ns and a maximum output power of 1.65 W, were consistently produced in a stable manner, while the launched power is 9.0 W with a slope efficiency of 18 %. The results indicates that the NiS₂ SA has great potential for pulse laser generation at mid-infrared region.

期刊介绍： The Journal covers the entire field of infrared physics and technology: theory, experiment, application, devices and instrumentation. Infrared'' is defined as covering the near, mid and far infrared (terahertz) regions from 0.75um (750nm) to 1mm (300GHz.) Submissions in the 300GHz to 100GHz region may be accepted at the editors discretion if their content is relevant to shorter wavelengths. Submissions must be primarily concerned with and directly relevant to this spectral region. Its core topics can be summarized as the generation, propagation and detection, of infrared radiation; the associated optics, materials and devices; and its use in all fields of science, industry, engineering and medicine. Infrared techniques occur in many different fields, notably spectroscopy and interferometry; material characterization and processing; atmospheric physics, astronomy and space research. Scientific aspects include lasers, quantum optics, quantum electronics, image processing and semiconductor physics. Some important applications are medical diagnostics and treatment, industrial inspection and environmental monitoring.
