Abstract: A frequency-stabilized light source emitting at 556 nm is realized byfrequency-doubling a 1112-nm laser, which is phase-locked to a fiber-basedoptical frequency comb. The 1112-nm laser is either an ytterbium Yb-dopeddistributed feedback fiber laser or a master-slave laser system that uses anexternal cavity diode laser as a master laser. We have achieved the continuousfrequency stabilization of the light source over a five-day period. With thelight source, we have completed the second-stage magneto-optical trapping MOTof Yb atoms using the 1S0 - 3P1 intercombination transition. The temperature ofthe ultracold atoms in the MOT was 40 uK when measured using the time-of-flightmethod, and this is sufficient for loading the atoms into an optical lattice.The fiber-based frequency comb is shown to be a useful tool for controlling thelaser frequency in cold-atom experiments.
