Abstract

For investigations of the mode content in fiber amplifiers for gravitational wave detectors, a spatial and spectral (S2) technique shall be used. We present a complete monolithic tunable fiber laser for real-time S2-measurements. Based on a Fabry-Perot tunable-filter, the laser achieves a wavelength-tuning-range of 100 nm with a linewidth of 1.9 GHz.
