1.55-μm Ce-Er-ZBLAN fiber laser operation under 980-nm pumping:: Experiment and simulation

Fiber laser operating property at 1.55-mum band in a newly developed Ce-Er-ZBLAN fiber by a continuous-wave laser diode pumping at 980 nm is presented. The output characteristics of the Ce-Er-ZBLAN fiber laser system are analyzed in detail based on the rate equations model by taking into account the energy transfer between Ce3+ and Er3+ ions, as well as the up-conversion mechanisms. The promotion role of the Ce in the erbium-doped ZBLAN for the 1.55-mum band fiber laser operation has been realized.
