The interferometric gravitational-wave detector LISA requires laser sources with 1W of output power and low frequency and power noise as well as actuators for further power and frequency stabilization. We report on power- and frequency noise measurements of an Yb-doped fiber amplifier seeded by a nonplanar ring oscillator and identify actuators for both power and frequency stabilization of such a system.
