Volume Bragg grating controlled fiber lasers
2012 (English)Conference paper, Abstract (Other academic)
In recent years, rare earth doped fiber lasers have experienced remarkable progress in terms of power scaling, warranting their use in numerous research and industry applications. Especially, the rapid rise in output powers an be attributed to the fact that the fiber laser design naturally promotes good thermal handling capabilities, over-all efficiency and exceptional spatial beam qualities. Moreover, the broad fluorescence spectra of the used rare earth gain media allow great flexibility in operating wavelength. However, proper restriction and stabilization of the spectral properties has to keep up with the rapid increase in power levels, without sacrificing the advantages of fiber lasers. In our work, we demonstrate how the implementation of volume-Bragg grating can cater for that demand. We show how this generic technology can be applied to increase the spectral brightness and to permit flexible wavelength-tuning and discuss its advantages and limitations with respect to other approaches.
