Abstract

We report on high-power operation of a widely tunable dual-wavelength Tm:fiber laser in the 2μm spectral region using volume Bragg gratings and a simple resonator configuration for wavelength selection. The wavelength splitting range is continuously tunable from 1 to 50nm (0.13.8THz), with >115W of diffraction-limited total output power for wavelength separations of <40nm. A maximum output power of 118W was obtained for 279W of launched pump power at 792nm, corresponding to a slope efficiency with respect to launched pump power of 45%. The prospects for further improvement in performance are discussed.
