Abstract: A fiber amplifier containing a waveguide activated with Er³⁺ ions was used for the first time to reduce the losses and thus improve the resolving power of a fiber Michelson interferometer. An interferometer with a path difference between the arms amounting to 5 km was constructed and the losses in this interferometer were fully compensated by the use of such an amplifier.
