Abstract:

The heat dissipation in active ytterbium and ytterbium–erbium glass elements when pumped using laser diodes was measured. It was found that, when the active medium is inverted to a level of 0.75𝑁Er0.75N_Er, depending on the concentration of ytterbium and erbium ions, 55%–70% of the total pump energy absorbed by the active element is converted into heat. The efficiency of the previously developed model of an active ytterbium–erbium medium for an adequate calculation of the heat generation in an active element is shown.
