Abstract

Characteristics of diode-pumped Er-doped and Er–Pr-codoped ZBLAN fiber amplifiers were investigated at the 2.72.8μm wavelength range. An amplified signal of 4.6W was obtained from the singly Er-doped amplifier for an input signal of 110mW, corresponding to a net gain of 16.2dB. An amplified signal of 2.65W was obtained from the Er–Pr-codoped amplifier for an input signal of 70mW, corresponding to a net gain of 15.8dB. It is found that the gain bandwidth of the singly Er-doped amplifier is much narrower than that of the Er–Pr-codoped amplifier. Small gain, no gain, or even a loss for shorter-wavelength signals propagating through the singly Er-doped amplifier should attribute for the large number residual populations in the lower laser level caused by the inefficient depopulation of the energy transfer upconversion processes.
