Abstract

The mid-infrared fiber lasers operating in the 3-5 μm have attracted great interest due to wide applications. However, the soft glass fiber-based rare-earth-doped laser in the mid-infrared band has limitations in power enhancement and wavelength expansion. Gas-filled hollow-core fiber lasers provide a new way to realize mid-infrared output. Here, we demonstrate an optically pumped CO-filled hollow-core fiber laser. The pump source was a homemade Tm fiber laser operating at 2.33 μm. By tuning the wavelength of the pump source, mid-IR emission from 4.64 to 4.82 μm has been achieved.
