We analyze the influence of heat generation caused by nonradiative transitions in a high-power 1.55 µm double-clad erbium-ytterbium fiber laser on the Stark level population. At strong pumping rates, 1 µm lasing can start as a result of parasitic reflections. We present a model that allows us to simulate the effect of self-generated heat on the Stark level population by using the MacCumber relation. Heat generation plays a significant role and improves the 1.5 µm laser's efficiency by increasing the 1 µm lasing threshold.
