Paper Abstract

We report on our research to develop a fiber Raman laser for multiple sodium laser guide star adaptive optics. Our goal is a fiber laser source at 589 nm with a diffraction-limited continuous-wave output power of at least 10 W and a linewidth of less than 3 GHz. In this paper we present and model our concept of a frequency-doubled fiber Raman amplifier. Recent advances in commercially available pump and seed laser technologies are making the amplifier approach a highly attractive solution for a turn-key sodium-guide star laser system.
