Abstract:
A simple set searching optimization algorithm is proposed for Er3+-Yb3+ co-doped fiber lasers in this paper. This method enables fiber lasers to acquire the optimum fiber length and Yb3+-Er3+ concentration ratio for a given accuracy. The numerical results illustrate that the optimum Yb3+-Er3+ concentration ratio changes very little, the optimum fiber length shortens and the corresponding output power is increased with erbium ions concentration increasing. The total Yb3+ and Er3+ contents are nearly constant under certain pump power, while the optimum total erbium ions and ytterbium ions are decreased with pump power decreasing.
