Title:
FIBRE LASER AMPLIFIER COMPRISING A LATERAL PUMPING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/061934
Kind Code:
A1
Abstract:
The present invention relates to a fibre optical amplifier, comprising an amplifying optical fibre (1), comprising a doped core (11), at least one optical cladding (12, 13) and an outer covering (14), the optical amplifier also comprising at least one lateral pumping device (2), comprising a pumping optical fibre (21) assembled with the amplifying optical fibre (1) at a junction zone (20). According to the invention, the outer covering (14) is made of a material with high thermal conductivity, covers most of the perimeter of the amplifying optical fibre (1) at the segments (101, 102) of this fibre which surround the junction zone (20), and covers part of this perimeter at the segment (103) of this fibre comprising the junction zone (20), so that the outer covering (14) extends without interruption on the amplifying optical fibre (1).
