Abstract
Efficient high-power operation of double-clad Er,Yb-doped fiber lasers with fixed-wavelength and wavelength-tunable resonator configurations using volume Bragg gratings for wavelength selection are reported. The fixed-wavelength laser yielded a maximum output power of at with a linewidth of (FWHM) for a launched pump power of at . The wavelength-tunable laser could be tuned from 1528 to with a linewidth of (FWHM) and with output power in the range for a launched pump power of . The prospects for further improvement in performance are considered.
