High-power tunable Er,Yb ribbon fiber laser
A high-power Er,Yb double-clad ribbon fiber laser pumped by a 9-diode-bar pump module is reported. The laser yielded 102 W of continuous-wave output at 1566 nm for a launched pump power of 244 W, corresponding to a slope efficiency of ~ 44% with respect to launched pump power.

Zusammenfassung: | A high-power Er,Yb double-clad ribbon fiber laser pumped by a 9-diode-bar pump module is reported. The laser yielded 102
W of continuous-wave output at 1566
nm for a launched pump power of 244
W, corresponding to a slope efficiency of ~
44% with respect to launched pump power. Tunable operation was achieved using a simple external feedback cavity with a diffraction grating and the operating wavelength could be tuned from 1533
nm to 1567
nm. Temperature distribution in the ribbon fiber geometry and prospects of power scaling will be discussed. |
