Abstract

We report the results of our power scaling experiments with resonantly cladding-pumped Er-doped eye-safe large mode area (LMA) fiber laser. While using commercial off-the-shelf LMA fiber we achieved over 88 W of continuous-wave (CW) single transverse mode power at ~1590 nm while pumping at 1532.5 nm. Maximum observed optical-to-optical efficiency was 69%. This result presents, to the best of our knowledge, the highest power reported from resonantly-pumped Yb-free Er-doped LMA fiber laser, as well as the highest efficiency ever reported for any cladding-pumped Er-doped laser, either Yb-co-doped or Yb-free.

Simplified optical layout of the cladding-pumped Yb-free Er fiber laser based on a COTS nLight/Liekki Er60-20/125 DC fiber resonantly pumped at 1532.5 nm. Laser cavity consists of the high reflectivity (one, of the choice of three, swappable, shown in Figure) dichroic mirror and the straight cleave at the output fiber end. Re-imaging optic at the pump end is not shown.

Fiber length optimization of the resonantly cladding-pumped Yb-free Er fiber laser based on a COTS nLight/Liekki Er60-20/125 DC fiber. CW laser output at 1590 nm versus absorbed pump power at 1532.5 nm is presented for the configuration shown in Fig. 1 with the FBG used as a pump mirror. Color coded data are: blue (solid pentagons and the line) – fiber length 21 m; red (downwards solid triangles and the line) – 16 m; wine (upwards solid triangles and the line) – 15 m; black (solid squares and the line) - 14 m. The highest slope efficiency of ~69% is achieved with the 15-m long fiber. The lowest slope efficiency of 63% was observed with the 21-m long fiber.
