Abstract
High-power laser generation in optical silica fibers doped with lanthanide atoms leads to its significant heating. Temperature of the active fiber core can exceed 80 °C [1]. Heating of the active fibers is mainly conditioned by the energy difference between pump and generated photons. Temperature rise can lead to thermal degradation of the protective polymer coating [2] and provoke other negative effects limiting maximum output power of the laser radiation. Therefore, there is a continuous search for new effective ways to reduce the active fiber heating and enlarge output laser power.
