Paper Abstract

In this communication, analytical expressions for the oscillation threshold pump power and the lasing efficiency of an erbium-doped fiber laser are derived from well-known equations that describe the amplification process in erbium-doped fibers. These expressions show the dependence of both the oscillation threshold pump power and the lasing efficiency on the cavity length. As a design criteria, an optimum fiber length is derived from the analytical expressions by maximizing the ratio between the lasing efficiency and the oscillation threshold pump power. Finally, theoretical results are given for the case of an erbium-doped fiber ring laser together with numerical calculations obtained by means of computer simulations.
