Paper Abstract

To optimize the performance of Er3+/Yb3+ co-doped double cladding fiber laser (EY-DCFL), the output characteristics of DBR EY-DCFLs with different parameters are investigated theoretically and experimentally. The output powers as functions of the launched pump power, the gain fiber length, as well as the reflectivity of the output mirror are presented by numerical simulation based on rate equations and power propagation equations. Experimental study on the output power, the spectral properties and the time-domain stability of DBR EY-DCFLs with different reflectivity is carried out. In the optimum condition, up to 2W output power at 1550.8nm is obtained with a slope-efficiency of 53.8% and a 3dB bandwidth of about 0.02nm.
