atom optics components that could be used in atom interferometers have been pro-posed or demonstrated (see, for example, Berman 1997). Our work in this area was guided by the desire to exploit a number of inherent advantages of atom interfer-ometers. (i) Laser cooling and manipulation techniques extend the interferometer

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.

A compact and robust frequency-doubled telecom laser system at 780 nm is presented for a rubidium cold atom interferometer using optical lattices.Adopting an optical switch at 1.5 µm and a dual-wavelength second harmonic generation system, only one laser amplifier is required for the laser system.Our system delivers a 900 mW laser beam with a detuning of 110 GHz for the optical lattice …

However, traditional Doppler cooling [4,5] relies upon the velocity dependence of a single narrow radiative transition and spontaneous emission to reset the atomic state. The cooling 2014-07-02 atom interferometer design developed at New York University (NYU) in the mid-1990s (Cahn et al., 1997). The interferometer involves the interac-tion of a set of pulsed laser ﬁelds with a sample of laser-cooled Rb atoms in a magneto-optical trap. A schematic of the experimental setup of this interferometer is shown in Figure 1.

4 Apr 2019 In atom interferometers, lasers with different frequencies are prepared to realize cooling and manipulation of the atomic cloud. Multiple laser We demonstrate an atom interferometer that uses a laser-cooled continuous beam of 87Rb atoms having velocities of 10–20 m/s. With spatially separated In atom interferometry, we use atoms that are laser-cooled to millionths of a degree above absolute zero. With pulses of light, we drive each atom into a quantum typical. Collisions between atoms at this velocity also collapse the quantum state used in atom interferometry, ruining the measurement.

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 …

Here, a DM is used to control the laser wavefront in an atom interferometer. We demonstrate its ability and effi-ciency to correct the wavefront aberrations in a proof-of-principle experiment realized with an atomic gravimeter. II. A laser system for a light-pulse atom interferometer typically includes a number of laser sources for cooling and for atom optics to meet different frequency detuning requirements at different stages of a measurement sequence. The number of laser units required makes the achievable minimum size and power of the instrument challenging, especially for space applications. We demonstrate a compact Laser cooling and trapping of metastable atoms. ( 1989 April -> 1990 March ) High power UV CW coherent light generation using sum-frequency mixing.
