OPTICAL SOURCE IMPLEMENTING A DOPED FIBRE, FIBRE FOR SUCH AN OPTICAL SOURCE AND METHOD FOR MANUFACTURING SUCH A FIBRE |
摘要 |
The invention relates to an optical source (1) having fibre emitting controlled single-transverse mode radiation at a wavelength of less than 1030 nm, including: at least one laser diode (2) suitable for emitting a pumping wave; and a section of sheathed amplifying optical fibre (6) having two ends, said amplifying optical fibre (6) comprising a core and a pumping sheath, the fibre being doped with a rare earth dopant; a means for coupling said pumping source in the sheath of said doped fibre, characterised in that the core of the doped fibre includes a cylindrical portion doped with a rare earth element selected among ytterbium, neodymium and thulium, in order to obtain a refractive index of the core that is higher than the refractive index of the sheath; the excitation wavelength of said laser diode (2) is between 780 nm and 960 nm; the diameter of the sheath is greater than 50 microns, and the surface ratio of the doped core to the pumping sheath is between 8 and 50. |
