Abstract
In this paper, we present a complete overview of the optical and noise performances of a high power single-frequency and single-mode fiber laser system operating at 780 nm. It provides up to 1.8W of linearly polarized output power at 780 nm, with 150 kHz linewidth and a perfect diffraction limited Gaussian beam. This newly developed fiber laser source is dedicated to trapping and cooling of Rb atoms for Bose-Einstein condensation or gravimetric applications. A great attention was paid to the laser intensity and frequency noises, linewidth and beam characterization of this all-fiber system.
