Light sources to implement the doped fiber, the light source for fiber, and method for producing the fiber

摘要

A light source (1) having a fiber for emission at wavelengths shorter than 1030nm, the emission of a single transverse mode is controlled, it is suitable for the release of the pumping wave at least the present invention, one laser diode ( and 2) has two ends, amplifying optical fiber with a sheath that contains a pumping sheath and core, rare earth elements are doped with (6) portion, the sheath of the fiber as the doped It is and means for coupling the pump source in, in order to obtain the refractive index of the core higher than the refractive index of the sheath, the core of the fiber as the doped, is selected ytterbium, neodymium, and thulium includes a cylindrical portion that rare earth elements were doped, and is between 960nm from 780nm, the diameter of the sheath is greater than 50 microns, the excitation wavelength of the laser diode (2) the core it is the doped relates to a light source (1), wherein is between 50 8 to surface ratio of the pumping sheath, that.
