Abstract :
We report on a tunable ytterbium-doped fiber laser bridging the gap from three-level lasing around 980 nm to true four-level lasing at 1066 nm. Wavelength-locking and -tuning was achieved by an external volume-Bragg grating (VBG). Results are compared with a numerical analysis based on a spectrally resolved rate equation analysis.
