We present the compact Gravimetric Atom Interferometer (GAIN), based on laser-cooled 87Rb atoms, and discuss its first measurements of the local gravitational acceleration.

and compresses the velocity distribution (i.e., cooling the atom sample). A single laser beam is sufﬁcient to cool a sample of trapped atoms or ions; however, free atoms must be irradiated with laser beams from all di-rections. For atoms with velocities that cause Doppler shifts comparable to the natural transition width (typi- Inherent advantages of atom interferometry 1. Laser cooling and manipulation techniques extend the interferometer measurement time, defined as the drift time of an atom through the interferometer, by orders of magnitude over interferometers based on photons, electrons or neutrons. 2.

Raman processes are employed to coherently manipulate the matter waves.

Wavelength of matter waves is much shorter, leading to The laser system must also be able to meet the requirements of a complex, modern cold atom system; it needs to cool atomic clouds launched from the atomic source to a 3D kinetic temperature in the range of a few mK, in a single magnetic substate, and in a narrow range of velocities along the axis of the laser interferometer.

Using stimulated Raman transitions between ground hyperfine states, 12 cycles of the interferometer sequence cool a freely moving atom cloud from 21 to 3 μK. This pulsed analog of continuous-wave Doppler cooling is effective at temperatures down to the recoil limit; with The atom interferometer laser source (AI laser) which provides the frequencies for laser cooling and trapping, detection and Raman transition is an erbium fiber DFB laser at 1.5 µm (output power 20 mW, linewidth 2 kHz). This laser source is locked relative to the rubidium transitions with a detuning that can be adjusted from 0 to −1 GHz. The laser system presented here is an entirely commercial device that can be adapted to atom interferometer experiments using atomic rubidium, as well as potassium 80 and cesium 81. These systems However, Weitz and Hänsch proposed utilising the velocity-dependent interferometer output to cool atoms and molecules with carefully timed laser pulse sequences, relaxing the constraints on laser Laser cooling techniques rely on the fact that when an object (usually an atom) absorbs and re-emits a photon (a particle of light) its momentum changes.

Measuring the fine-structure constant with atom interferometry constitutes a low-energy, tabletop search for physics beyond the Standard Model, like dark matter. These measurements require laser cooling to slow particles and permit the long observation times required for sufficient precision and full quantum control.
