英文摘要	An optical source having a fiber emitting controlled single-transverse mode radiation at a wavelength of less than 1030 nm, includes at least one laser diode suitable for emitting a pumping wave; and a section of sheathed amplifying optical fiber having two ends, the amplifying optical fiber comprising a core and a pumping sheath, the fiber being doped with a rare earth dopant; a device for coupling the pumping source in the sheath of the doped fiber, characterized in that the core of the doped fiber 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 the laser diode is between 750 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.
