“…A detailed review of "early" demonstrations can be found in [3]. In the last ten years, the field of applications of FSF lasers have spread to various areas, such as manipulation of atoms by laser [4,5,6], optical communications [7], optical frequency combs [8,9] and optical frequency domain ranging [10,11,12,13].…”

International audienceThe use of frequency-shifted feedback (FSF) lasers in optical metrology is based on a unique coherence property: the appearance of beats in the noise spectrum at the output of a two-beam interferometer, whose frequencies vary linearly with the path delay of the interferometer. A description of the output of a FSF laser as a moving comb of optical frequencies is generally admitted to explain these specific coherence properties. Here starting from the model of a passive FSF cavity seeded by spontaneous emission we give a rigorous description of the time-spectrum properties of FSF lasers and show that the moving comb exists only in the limit of small frequency shift

“…Early work using specific properties of the FSF laser concerned the mechanical action of light on atoms, such as slowing and cooling of atoms in a beam [39] following up on a proposal by [40] or light-induced drift separation of Rb isotopes [41]. Further applications include accurate frequency-interval measurements [42]; efficient optical pumping of atoms [43,44]; efficient excitation of atoms in the higher atmosphere for preparation of a guide star [45,46,47]; observation of dark resonances in optical excitation of atoms [48]; realization of a FSF laser with high [49] or ultrahigh and variable [50] pulse rate; control of pulse duration [51] or new schemes for frequency stabilization [52]; rapid tuning of frequency [53]; and generation of a frequency comb for specific tasks in underwater sensing [54].…”

We report results on ranging based on frequency shifted feedback (FSF) lasers with two different implementations: (1) An Ytterbium-fiber system for measurements in an industrial environment with accuracy of the order of 1 µm, achievable over a distance of the order of meters with potential to reach an accuracy of better than 100 nm; (2) A semiconductor laser system for a high rate of measurements with an accuracy of 2 mm @ 1 MHz or 75 µm @ 1 kHz and a limit of the accuracy of ≥ 10 µm. In both implementations, the distances information is derived from a frequency measurement.The method is therefore insensitive to detrimental influence of ambient light. For the Ytterbium-fiber system a key feature is the injection of a single frequency laser, phase modulated at variable frequency Ω, into the FSFlaser cavity. The frequency Ω max at which the detector signal is maximal yields the distance. The semiconductor FSF laser system operates without external injection seeding. In this case the key feature is frequency counting that allows convenient choice of either accuracy or speed of measurements simply by changing the duration of the interval during which the frequency is measured by counting. 2 J.
