We present a new theoretical scheme for an Ho~(3+)-doped athermal high-power continuous-wave amplifier. This approach, with two optical pump sources, allows amplification without detrimental heating. Athermal amplification is achieved by the balance between heating generated during the amplification process, which involves ~5I_8 and ~5I_7 levels, and laser cooling with anti-Stokes fluorescence, which involves the ~5I_8 and ~5I_6 levels. For athermal operation, the pump power providing the cooling has to be distributed properly along the length of the amplifier.
