Cold atom experiments usually require a whole set of lasers with different and precisely defined optical frequencies. A frequency comb offers the possibility to stabilize all lasers in the visible and near IR part of the spectrum (and even far beyond in the IR regime if needed) to the same reference, thereby providing the same stability and accuracy as well as mutual coherence to all lasers. We present a setup in which a frequency comb is used to stabilize more than 20 CW Lasers in 7 different laboratories. The comb light is distributed via optical fibers from the central comb laboratory to all other labs. Many applications, like quantum information experiments with single atoms and photons or molecular spectroscopy can be simplified with this setup and allows for reliable operations with improved accuracy.
