Abstract

The critical power level provides an objective tool for the determination of the maximum power available in a fiber laser based on physical parameters as: core diameter, temperature, and absorption and emission cross section for both the pump and laser wavelengths. This work presents a theoretical study of critical power levels when Ytterbium-doped fibers are exposed to changes of temperature. We found that critical power curves extend their wavelength dependence, ranging from 1 μm to 1.2 μm when fibers were heated up 300°K. Also we found that critical power values are large than those obtained in conditions of room temperature. While low critical powers were obtained at lower temperatures (around 77°K) with a reduced interval of wavelengths from 1 μm to 1.1 μm.
