Fiber-comb-stabilized light source at 556 nm for magneto-optical trapping of ytterbium

Masami Yasuda, Takuya Kohno, Hajime Inaba +4 more

A frequency-stabilized light source emitting at 556 nm is realized by frequency doubling a 1112 nm laser, which is phase locked to a fiber-based optical frequency comb. The 1112 nm laser is either an ytterbium (Yb)-doped distributed feedback fiber laser or a master-slave laser system that uses an external cavity diode laser as a master laser. We have achieved the continuous frequency stabilization of the light source over a 5 day period. With the light source, we have completed the second-stage magneto-optical trapping (MOT) of Yb atoms using the S10–P31 intercombination transition. The temperature of the ultracold atoms in the MOT was 40 μK when measured using the time-of-flight method, 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 the laser frequency in cold-atom experiments.A frequency-stabilized light source emitting at 556 nm is realized by frequency doubling a 1112 nm laser, which is phase locked to a fiber-based optical frequency comb.

Ultracold Atom Gravimeter

Sébastien Merlet, Romain Karcher, Almazbek Imanaliev +1 more

Atom interferometry allows for the realisation of inertial sensors based on laser cooled atoms. Their limits in performances, both in terms of accuracy and stability, are linked to the temperature of the atomic cloud, in the low μK range, and more specifically, to the residual ballistic expansion of the atomic sources in the laser beams. To overcome these limits, we use as a source ultracold atoms in the nano-kelvin range in our absolute atom gravimeter.
