A simplified model based on the weakly guiding waveguide approximation is proposed for estimating the effects occuring during propagation of radiation in a double-clad active cone optic fiber. This model is used for computer simulation, whose results agree with obtained experimental data. Practical recommendations on optimizing the shape of the cone fiber and the aperture of the pumping source for enhancement of the pump absorption efficiency are given.
