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

Fiber laser operating property at 1.55-μm 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 Ce/sup 3+/ and Er/sup 3+/ ions, as well as the upconversion mechanisms. The promotion role of the Ce in the erbium-doped ZBLAN for the 1.55-μm band fiber laser operation has been realized.
