Abstract

Lasing from HBr-filled hollow-core fiber (HCF) based on population inversion is demonstrated and characterized. Usually, there are two emission lines corresponding to each absorption line. Here, by controlling the gas pressure in the HCF, a single emission line P(7) of 4.26 μm is efficiently achieved when pumping with line R(5) of 1958 nm, and the other emission line R(5) of 3.91 μm is totally suppressed. The maximum 4.26 μm laser output power of 350 mW is obtained with a slope efficiency of about 11%.
