Zusammenfassung:	The invention relates to a power laser device that can particularly be used for lidar systems, and to an amplification system including such a device. The device includes a fibered input segment (1) for amplifying a multi-modal incident optical beam (3), a fibered conversion segment (4) for converting the multi-modal incident optical beam into a power single-mode beam (8), and a fibered intermediated segment (9) for propagating the multi-modal incident optical beam (3) towards the fibered conversion segment (4) so that the reflected single-mode optical beam (8) can exit the device. The invention also relates to a power single-mode amplification system including the power single-mode laser device of the invention. La présente invention se rapporte à un dispositif laser de puissance, notament utilisable pour des systèmes lidars, ainsi qu'à un système d'amplification comportant le dispositif. Le dispositif comprend un tronçon fibré d'entrée (1) destinées à amplifier un faisceau optique incident multimodes (3), un tronçon fibré de conversion (4) destinée à la conversion du faisceau optique incident multimodes en un faisceau monomode de puissance (8) et un tronçon fibré intermédiaire (9) permettant au faisceau optique incident multimodes (3) de se propager vers le tronçon fibré de conversion (4) et permettant au faisceau optique monomode réfléchi (8) de sortir du dispositif. L'invention a aussi pour objet un système d'amplification monomode de puissance comportant le dispositif laser monomode de puissance de l'invention.
