Abstract

Mid-infrared fiber lasers have shown out standing prospects in many fields, so mid-infrared fiber Bragg grating (FBG) as the most essential component in mid-infrared fiber laser oscillators has attracted much attention. Here, we fabricated mid-infrared FBGs on ZBLAN fibers operating nearby 2.8-2.9 μm by femtosecond laser direct inscription technique, and measured their transmission spectra by all-fiber measurement system, which lays the foundation of high-power all-fiber mid-infrared laser oscillators near 2.8 μm.
