摘要：

We analyze the influence of heat generation caused by nonradiative transitions in a high-power 1.55 mu m double-clad erbium-ytterbium fiber laser on the Stark level population. At strong pumping rates, 1 mu m 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 mu m laser's efficiency by increasing the 1 mu m lasing threshold. (c) 2005 Optical Society of America
