Abstract

Laser à fibre dont la fibre enroulée comportant une âme et une gaine. La fibre, qui est pompée par une source d'énergie, produit un faisceau laser de grande qualité. La fibre est enroulée à plat, avec ses deux extrémités tournées vers l'extérieur de l'enroulement. La fibre enroulée est pompée optiquement par une source optique située le long d'un bord de l'enroulement. Selon un mode de réalisation, la fibre est pompée par une barrette de diodes laser à couplage serré. La fibre comporte une âme dopée en terre rare entourée d'un matériau de gainage.
