Abstract
A Tm-doped large mode area (LMA) silica fiber laser has been locked to a stable wavelength of using a volume Bragg grating (VBG). The measured spectral width of the laser output was , limited by the spectrometer resolution. Although this laser had modest output and slope efficiency (41%), this new approach to spectrally limiting the output of LMA fiber lasers is inherently extendable to kilowatt powers, opening up several applications including high-power pulsed fiber lasers and spectral beam combining. Performance characteristics of the laser compared to one using a dielectric mirror as a high reflector are described, and the results imply low VBG losses.
