Title

Volume Bragg Grating Stabilized Spectrally Narrow Tm Fiber Laser

Abstract

A Tm-doped large mode area (LMA) silica fiber laser has been locked to a stable wavelength of 2053.9 nm using a volume Bragg grating (VBG). The measured spectral width of the laser output was <300 pm, limited by the spectrometer resolution. Although this laser had modest output (∼5W) 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. © 2008 Optical Society of America.
