Abstract

Large mode area (LMA) Yb-doped double clad fiber lasers with high power are theoretically and experimentally investigated. For a Fabry-Perot cavity structure, we show the dependence of output power on the output mirror reflectivity, coupled pump power and fiber length, respectively by using power propagation equations and rate equations. Stable CW operation of the fiber laser at 1064 nm with maximum power 4.6 W and slope efficiency 82.6% is achieved in the experiment.
