Abstract

Gas-discharge fiber lasers (GDFLs) based on hollow-core fibers filled with noble-gas mixtures are investigated. Laser parameters of plasma in GDFLs are measured for the first time. By applying Rigrod's analysis to the GDFLs with different lengths of active medium, small-signal gain coefficients and saturation powers are determined for several laser transitions in the range of 2-2.5 µm in GDFLs based on He:Xe, He:Ar and He:Kr gas-mixtures. The prospects of increasing the GDFLs output power are discussed.
