Abstract

We present a theoretical scheme for a Tm³⁺-doped radiation-balanced (athermal) continuous-wave fiber amplifier. This mode of operation allows amplification without detrimental heating of the fiber with optical pumping. Athermal amplification is realized by laser cooling in which waste heat is disposed of in the form of spontaneous fluorescence by balancing the radiated and absorbed power. The athermal fiber amplification can be realized using a specially designed distributed pumping scheme.
