Paper Abstract

The paper discusses the factors affecting the pump quantum efficiency for three-micron stationary emission in concentrated Er systems, driven by the up-conversion processes from the terminal laser level. It is shown that in the stationary regime analytical formulae for the quantum efficiency could be obtained as a function of pump conditions and global efficiency of the cross-relaxation processes. These formulae enable a selection of the active medium and pump conditions in order to obtain high pump efficiency.
