Paper Abstract

A theoretical model based on propagation-rate equations has been developed for modeling the continuous wave operations of Er3+/Yb3+ co-doped fiber lasers. It includes uniform upconversion mechanisms from the 4I13/2 and 4I11/2 erbium levels and describes the coupling between Er3+ and Yb3+ ions through a pair-induced energy transfer process. The nonlinear differential equations of the model are numerically solved by means of a Runge-Kutta based iterative procedure. Numerical results, based on realistic input fiber parameters, show that slope efficiencies close to the quantum limit with threshold pump powers of few mW, can be achieved in short Er3+/Yb3+ co-doped fibers equipped with input dielectric mirrors and output grating Bragg reflectors. Furthermore, we show that single frequency cw operations can also be performed, with lower efficiency, in Er3+/Yb3+ co-doped Fabry-Perot fiber microlasers
