“…During experiments the fiber was placed in a free coil on a table and no additional cooling was required. To date the power of 103 W is the highest value ever reported for Ytterbium-free Erbium-doped fiber lasers pumped at 976 nm and it is equal to that of the in-band pumped Er-doped fiber lasers 7,9 . Also pump-conversion efficiency of 37 % is a record value for both Erbium and Erbium-Ytterbium single-mode 100 W class fiber lasers pumped at 976 nm.…”

“…To the best of our knowledge the highest "wall-plug" efficiency for in-band pumped Erbium-doped lasers was demonstrated in Ref. [9] where Erbium-doped fiber was cladding-pumped by 19 combined Erbium-Ytterbium lasers at 1532 nm. Taking into account 50 % 970 nm diode, <35 % Erbium-Ytterbium laser 3 and 71 % Erbium doped fiber efficiencies overall electrical-to-1.55 µm efficiency was not higher than 13 %.…”

Power scaling of Yb-free Er-doped fiber lasers is extremely challenging due to low Er ion absorption cross-section and growth of unbleachable loss at high Er concentrations because of clustering effects. Hence, usual double-clad Er-doped fibers suffer from low efficiency. We present an efficient high power all-fiber amplifier based on our newly developed Yb-free Er-doped fiber. Proper core composition and relatively low Er3+ concentration mitigates clustering effect. Furthermore, large single-mode core diameter of 34 um increases the pump absorption and decreases the fiber length. Our amplifier consists in the specialty Er fiber pumped through a commercially available pump combiner by means of 6 pigtailed multimode diodes (D=105 um, NA=0.15, input pump power of 275W). The signal source is a low power continuous wave fiber laser spliced to the amplifier. Therefore we built truly all-fiber laser without any free space coupling. We obtained 103 W of amplified signal limited only by the available pump power. Pump conversion efficiency is as high as 37 %. To the best of our knowledge this is the highest power ever demonstrated for Yb-free Er-doped lasers pumped at 976 nm. This power level is similar to that obtained in resonantly pumped Er-doped fiber lasers.

“…Single-mode all-fiber Er,Yb codoped laser systems have naturally become an attractive candidate for achieving high output power level while maintaining good laser beam quality to meet the requirement for particular applications. Nowadays, more than 10 W output powers of single-mode laser emissions at ∼1.5 m in the Er,Yb codoped laser systems have been achieved based on the more complex master oscillator power amplifier (MOPA) configurations [7,8], while the extremely simple all-fiber Er,Yb codoped fiber laser oscillators still remain of a limited output power level of several watts [9][10][11].…”

We report a high-power cladding-pumped Er,Yb codoped all-fiber laser with truly single transverse mode output. The fiber laser is designed to operate at 1545 nm by the use of a pair of fiber Bragg gratings (FBGs) to lock and narrow the output spectrum, which can be very useful in generating the eye-safe ~1650 nm laser emission through the Stimulated Raman Scattering (SRS) in silica fibers that is of interest in many applications. Two pieces of standard single-mode fibers are inserted into the laser cavity and output port to guarantee the truly single-mode output as well as good compatibility with other standard fiber components. We have obtained a maximum output power of 19.2 W at 1544.68 nm with a FWHM spectral width of 0.08 nm, corresponding to an average overall slope efficiency of 31.9% with respect to the launched pump power. This is, to the best of our knowledge, the highest output power reported from simple all-fiber single-mode Er,Yb codoped laser oscillator architecture.
