“…In [4,[6][7][8], it was shown that the highest PCE in Er-doped fibers can be obtained using an aluminosilicate glass matrix with a concentration of Al 2 O 3 in excess of 3 mol.%. This glass matrix allow one to achieve a very high gain per length [9][10][11], which makes possible even building DFB Er-doped fiber lasers [12,13]. However, such a compound is not suitable for the fabrication of single-mode fibers with large core diameters because of the high (more than 0.14) core numerical aperture (NA).…”

Double-clad Er-doped fibers highly doped with aluminum (up to 3 mol.%) and fluorine (up to 1.5 wt.%) have been fabricated and studied. The fibers have a core numerical aperture of approximately 0.055, which allowed us to achieve a single-mode propagation regime for a fiber core diameter of 35 µm. The possibility of increasing the pump-to-signal conversion efficiency in the L-band using the developed double-clad Er-doped fibers was demonstrated. Utilization of the F-GeO 2 -Al 2 O 3 -SiO 2 -Er fiber together with a P 2 O 5 -Al 2 O 3 -SiO 2 -Er fiber was found to be promising for single-frequency amplifiers because the fibers have negligible overlap of the stimulated Brillouin scattering gain. This feature allowed us to build a cascaded double-clad Er-doped fiber amplifier (two Er-doped fibers of different types were spliced one by one) with a threshold of stimulated Brillouin scattering greater than that of an amplifier based on a single Er-doped fiber with the same net length and pump-to-signal conversion efficiency.
