“…We believe a more engineered version of this laser system could compete in terms of compacity, stability and cost with laser systems based on frequency doubling of telecom fibered sources. In particular, such laser systems could for instance benefit from the development of microintegrated diode lasers [34] or high power narrow linewidth DFB lasers [35], and from the engineering efforts undertaken for developing such laser systems for space applications [5,11,36,37].…”

We present here a simple laser system for a laser cooled atom interferometer, where all functions (laser cooling, interferometry and detection) are realized using only two extended cavity laser diodes, amplified by a common tapered amplifier.One laser is locked by frequency modulation transfer spectroscopy, the other being phase locked with an offset frequency determined by an Field-Programmable Gate Array (FPGA) controlled Direct Digital Synthesizer (DDS), which allows for efficient and versatile tuning of the laser frequency. Raman lasers are obtained with a double pass acousto-optic modulator. We demonstrate a gravimeter using this laser system, with performances close to the state of the art.

We describe a simple and compact architecture for generating all-optical frequencies required for the laser cooling, state preparation, and detection of atoms in an ultracold rubidium-87 experiment from a single 780 nm laser source. In particular, repump light ∼6.5 GHz away from the cooling transition is generated by using a highbandwidth fiber-coupled electro-optic modulator (EOM) in a feedback loop configuration. The looped repump light generation scheme solves the problem of the limited power handling capabilities characteristic of fiber EOMs. We demonstrate the functionality of the system by creating a high-atom-number magneto-optical trap (MOT).
