Experimental study of phenomenological model of Yb fiber amplifier

Research output: Chapter in Book/Report/Conference proceedingConference contributionResearchpeer-review


The paper compares the simplest phenomenological model of a saturable fiber amplifier based on Yb-doped fiber with experimental measurements. The numerical parameters of this model and their dependence on the optical pumping power of laser diodes are determined. It is shown that the model under study gives an error in determining the output power from the amplifier of less than 5% in the range of input powers from 0.29 to 14 nJ in the pump power range 0.5 to 3.5 W. The output parameters of a numerical model of a mode-locked fiber laser and its experimental realization are compared. The obtained results can be used in numerical modeling and design of fiber laser systems.
