4. Applications

In this section, we present the major industrial and scientific fields in which fiber lasers are used, as well as a few more marginal applications that nevertheless demonstrate the advantages of these sources. Of course, this brief presentation does not claim to be exhaustive, and the field of applications is evolving rapidly with technological developments.

4.1 Optical telecommunications

Rare earth-doped fibers have historically been developed in the context of fiber optic telecommunications. Indeed, the development of erbium-doped fiber amplifiers has led to an explosion in the performance of these systems in terms of throughput-distance product, by eliminating the need for regenerative repeaters based on fast electronics. In fiber telecommunications systems,...
