FIELD: physics.
SUBSTANCE: invention relates to laser equipment. Active medium for fiber lasers contains a structurally-activated epoxy oligomer with molecules of organic dyes and a hardener. Curing agent used is finely dispersed glass with chemically activated reactive groups on the surface, with the following ratio of ingredients, pts. wt.: organic dye 0.0075–0.1; epoxy oligomer 8.0–31.5; fine-dispersed glass with chemically activated surface 68.4925–91.9.
EFFECT: technical result consists in enabling adjustment of the value of the refractive index of the active fibre core.
