Abstract

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.
