Query: Narrow linewidth single laser source system for onboard atom
  interferometry   A compact and robust laser system for atom interferometry based on a
frequency-doubled telecom laser is presented. Thanks to an original
stabilization architecture on a saturated absorption setup, we obtain a
frequency-agile laser system allowing fast tuning of the laser frequency over 1
GHz in few ms using a single laser source. The different laser frequencies used
for atom interferometry are generated by changing dynamically the frequency of
the laser and by creating sidebands using a phase modulator. A laser system for
Rubidium 87 atom interferometry using only one laser source based on a
frequency doubled telecom fiber bench is then built. We take advantage of the
maturity of fiber telecom technology to reduce the number of free-space optical
components (which are intrinsically less stable) and to make the setup compact
and much less sensitive to vibrations and thermal fluctuations. This source
provides spectral linewidth below 2.5 kHz, which is required for precision atom
interferometry, and particularly for a high performance atomic inertial sensor.
