LASER A FIBRE DE PUISSANCE A CONVERSION DE MODE |
| 摘要 |
The invention concerns a pumped fibre laser comprising essentially a doped fibre (1), Said laser is mainly characterised in that the doped fibre is multimode (1) and it also comprises a spatial mode converting device (3) receiving the beam. Said multimode fibre has a core with diameter greater than 30 micrometers, even greater than 50 micrometers.
