Abstract

An optical gain of 35 dB at 2.716 μm signal wavelength has been measured in an erbium doped ZBLAN fibre. A pump-wavelength scanning determined the pump wavelength for maximum gain. This pump wavelength was found to be 0.642 μm. The maximum absorption wavelength for this Er³⁺ doped fibre is 0.649 μm. It was deduced that the excited state absorption process improves the gain performance of such fibres at the signal wavelength considered.
