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.

Long-distance measurements (10 m -1000 m) with an accuracy of 10 -7 is a challenge for many applications. We show that it is achievable with Frequency Shifted Feedback (FSF) laser interferometry technique, provided that the determination of the radio frequency beat order be made without ambiguity and on a time scale compatible with atmospheric applications. Using the pulsed-FSF laser that we developed for laser guide star application, we propose and test, up to 240 m, a simple method for measuring the beat order in real time. The moving-comb and Yatsenko models are also discussed. The first of these models fails to interpret our long-distance interferometry results. We show that the accuracy of long-distance measurements depends primarily on the stabilization of the acoustic frequency of the modulator.

“…Optical frequency comb provided by the mode-locked fiber lasers has already found application in precision metrology, optical spectroscopy, THz generation and many others. Recently, frequency-shifted feedback lasers were considered as potential light sources for applications in optical reflectometry, frequency measurements, spectroscopy, optical ranging, imaging and medical diagnosis [1][2][3][4][5][6]. If the introduced frequency shift is in proper relation to the axial mode frequency difference, FSF laser can operate in mode-locked regime [5].…”
