Abstract

We demonstrate, for the first time, Ramsey CPT spectroscopy with a miniature electro-optical bench associated to a dual-frequency generator based on combined optical injection locking and optical phase locking techniques Preliminary results show Ramsey CPT resonance with a contrast of 2% at the Cesium D2 line. Frequency difference locking loops lead to a contribution of Dick effect to fractional frequency stability lower than 1.7x10-13 at 1 s, in line with targeted clock stability of 5x10-13 at 1 s.

Abstract

The Matter-wave laser Interferometric Gravitation Antenna (MIGA) is an underground instrument using cold-atom interferometry to perform precision measurements of gravity gradients and strains. Following its installation at the low noise underground laboratory LSBB in the South-East of France, it will serve as a prototype for gravitational wave detectors with a horizontal baseline of 150 meters. Three spatially separated cold-atom interferometers will be driven by two common counter-propagating lasers to perform a measurement of the gravity gradient along this baseline. This article presents the cold-atom sources of MIGA, focusing on the design choices, the realization of the systems, the performances and the integration within the MIGA instrument.

Abstract

We present a compact atomic clock using cold rubidium atoms based on an isotropic light cooling, a Ramsey microwave interrogation and an absorption detection. Its technology readiness level is suitable to industrial transfer. We use a fibre optical bench, based on a frequency-doubled telecom laser. The isotropic light cooling technique allows us to cool down the atoms in 100 ms and works with a cycle time around 200 ms. We carried out measurements in simulated microgravity and obtained the narrowest fringes ever recorded in microgravity., Comment: 7 pages, 6 figures

Abstract

We report on telecom laser frequency stabilization to narrow iodine hyperfine line in the green range of the optical domain, after a frequency tripling process using two nonlinear PPLN crystals. We have generated up to 300 mW optical power in the green (P3w), from 800 mW of infrared power (Pw). This result corresponds to an optical conversion efficiency eta= P3w/Pw ~ 36 %. To our knowledge, this is the best value ever demonstrated for a CW frequency tripling process. We have used a narrow linewidth iodine hyperfine line (component a1 of the 127I2 R 35 (44-0) line) to stabilize the IR laser yielding to frequency stability of 4.8x10-14 t-1/2 with a minimum of 6x10-15 reached after 50 s of integration time. The whole optical setup is very compact and mostly optically fibered. This approach opens the way for efficient and elegant architecture development for space applications as one of several potential uses., Comment: in 30th European Frequency and Time Forum (EFTF'2016), 4th - 7th April 2016, York, United Kingdom

Abstract

We transferred the frequency of an ultra-stable laser over 86 km of urban fiber. The link is composed of two cascaded 43-km fibers connecting two laboratories, LNE-SYRTE and LPL in Paris area. In an effort to realistically demonstrate a link of 172 km without using spooled fiber extensions, we implemented a recirculation loop to double the length of the urban fiber link. The link is fed with a 1542-nm cavity stabilized fiber laser having a sub-Hz linewidth. The fiber-induced phase noise is measured and cancelled with an all fiber-based interferometer using commercial off the shelf pigtailed telecommunication components. The compensated link shows an Allan deviation of a few 10-16 at one second and a few 10-19 at 10,000 seconds.

6. Influence of optical aberrations in an atomic gyroscope

Abstract

In atom interferometry based on light-induced diffraction, the optical aberrations of the laser beam splitters are a dominant source of noise and systematic effect. In an atomic gyroscope, this effect is dramatically reduced by the use of two atomic sources. But it remains critical while coupled to fluctuations of atomic trajectories, and appears as a main source of noise to the long term stability. Therefore we measure these contributions in our setup, using cold Cesium atoms and stimulated Raman transitions.

Abstract

International audience; We report on the development of an optical frequency standard (OFS) operating in the C-Telecom band, stabilized in the 10-15 range, using Doppler-free spectroscopy of iodine hyperfine line around 514 nm. To bridge the frequency gap between infrared (IR) and green domains, we operate an efficient frequency tripling process of the IR laser diode, with two cascaded nonlinear Lithium Niobate crystals. We have implemented an original optical arrangement which allows a high efficiency optical power conversion (P  P), yielding to 300 mW at 514 nm. The generated green optical power is 20 times higher than the optical level required for the frequency stabilization purpose. We have demonstrated a residual frequency instability of 4.8 x 10-14 τ-1/2 with a minimum value of 6 x 10-15 conferred to a butterfly laser diode emitting at 1542 nm. A novel demonstrator-fully fibered iodine stabilized laser system is under development to match several space missions requirements

Abstract

International audience; We report on a Telecom laser diode (LD) frequency stabilization to a narrow iodine hyperfine line in the green range, after frequency tripling process using fibered nonlinear waveguide PPLN crystals. We have generated up to 300 mW optical power in the green range (~514 nm) from 800 mW of infrared power (~1542 nm), corresponding to a nonlinear conversion efficiency  = P3/P ~ 36%. Less than 10 mW of the generated green power are used for Doppler-free spectroscopy of 127I2 molecular iodine, and therefore- for the frequency stabilization purpose. The frequency tripling optical setup is very compact (< 5 l), fully fibered, and could operate over the full C-band of the Telecom range (1530 nm 1565 nm). Several thousands of hyperfine iodine lines may thus be interrogated in the 510 nm 521 nm range. We build up an optical bench used at first in free space configuration, using the well-known modulation transfer spectroscopy technique (MTS), in order to test the potential of this new frequency standard based on the couple 1.5 µm laser / iodine molecule. We have already demonstrated a preliminary frequency stability of 4.8 x 10-14  -1/2 with a minimum value of 6 x 10-15 reached after 50 s of integration time, conferred to a laser diode operating at 1542.1 nm. We focus now our efforts to expand the frequency stability to a longer integration time in order to meet requirements of many space experiments, such earth gravity missions, inters satellites links or space to ground communications. Furthermore, we investigate the potential of a new approach based on frequency modulation technique (FM), associated to a 3rd harmonic detection of iodine lines to increase the compactness of the optical setup.

Abstract

The increasing performance of optical lattice clocks has made them attractive for scientific applications in space and thus has pushed the development of their components including the interrogation lasers of the clock transitions towards being suitable for space, which amongst others requires making them more power efficient, radiation hardened, smaller, lighter as well as more mechanically stable. Here we present the development towards a space-compatible interrogation laser system for a strontium lattice clock constructed within the Space Optical Clock (SOC2) project where we have concentrated on mechanical rigidity and size. The laser reaches a fractional frequency instability of 7.9 × 10−16 at 300 ms averaging time. The laser system uses a single extended cavity diode laser that gives enough power for interrogating the atoms, frequency comparison by a frequency comb and diagnostics. It includes fibre link stabilisation to the atomic package and to the comb. The optics module containing the laser has dimensions 60 × 45 × 8 cm3; and the ultra-stable reference cavity used for frequency stabilisation with its vacuum system takes 30 × 30 × 30 cm3. The acceleration sensitivities in three orthogonal directions of the cavity are 3.6 × 10−10/g, 5.8 × 10−10/g and 3.1 × 10−10/g, where g ≈ 9.8 m/s2 is the standard gravitational acceleration.

Abstract

Coherent population trapping (CPT) of metal-alkali atoms is an interesting technique for the development of compact atomic frequency references; it relies on the excitation of the atoms by two phase-coherent laser fields. We describe the design and operation of an innovating dual-frequency laser source dedicated to Cs CPT atomic clocks, based on the direct dual-frequency and dual-polarization operation of an optically-pumped semiconductor laser at 852 nm. The phase noise of beatnote generated by the laser source is at maximum of -90 dBrad²/Hz with active stabilization, and the relative intensity noise (RIN) has been measured at -115 dB/Hz. It would potentially results in a clock frequency stability of 1.6 .10^-12 at 1 second, limited by the laser RIN. With proper adjustments in the laser and clock set-up, we target a stability of 3.10^-13 at 1 second.

Abstract

International audience; The availability of small atomic clocks should greatly improve the mobility and robustness of, for example, satellite positioning system and high bitrate communication networks. In this context, coherent population trapping (CPT) is an interesting technique for the development of compact atomic references. It is based on the coupling of the two hyperfine ground states of an alkali atom, through excitation to a common atomic level, by two phase-coherent laser fields. We propose an innovating laser source for the production of such bifrequency field based on the dual-frequency and dual-polarization operation of an optically-pumped vertical external-cavity semiconductor laser (OP-VECSEL). Laser noise contributions to clock performance have been evaluated and results in an estimated clock frequency stability of 2.7 x 10-12 over a second limited by laser intensity noise. Stability level below 3 x 10-13 over one second is reasonably reachable with small changes in clock working conditions or laser set-up.

Abstract

National audience; Nous décrivons l'émission simultanée en phase, sur deux fréquences optiques polarisées perpendiculairement, d'un laser à semiconducteur en cavité externe pompé optiquement. L'émission est accordable autour de la raie D2 du césium à 852,14 nm avec une puissance optique d'environ 13 mW sur chaque polarisation. La différence de fréquence est ajustée grâce à un modulateur électro-optique autour de 9,2 GHz. Nous évaluons la source réalisée en vue de son application au piégeage cohérent de population d'atomes de césium dans une horloge atomique.

Abstract

The purpose of my thesis was to use the recent developments of atom laser manipulation to build a device that can measure rotation rate as accurately as the best optical gyroscopes. Like optical gyroscopes, atomic gyroscopes are based on the Sagnac effect. The Sagnac effect consists in a extra phase shift at the output of a non zero area interferometer, when it is rotating. We show that the Sagnac effect for matter waves of Cesium atoms, for example, is 1011 times more sensitive than for optical waves. The main difficulty concerning the device is to coherently separate and recombine the atomic waves. We do this in the interaction zone thanks to two-photon transitions called stimulated Raman transitions. The impulsions of the two photons, once transferred to the atom, is what provokes the angular separation for the two atomic wave packets. Building the device implied finding many new technical solutions, which proved to work well. One of the main problems was to build a device small enough, and as unchanged by outside parameters (magnetic fields, temperature, etc.) as possible, to be transportable. Our atomic source is a laser cooled atom source, which allows a small interaction zone while maintaining a very good level of performance. The device is also sensitive to accelerations ; a counter-propagating double atomic jet technique has therefore been used to discriminate between rotation and acceleration phase shift., L'objectif de la thèse était d'utiliser les développements de la manipulation d'atomes par lasers pour réaliser un appareil capable de mesurer les vitesses de rotation avec une sensibilité équivalente à celle des meilleurs gyromètres optiques. Les gyromètres atomiques, comme les gyromètres optiques sont fondés sur l'effet Sagnac. Cet effet est l'apparition d'un déphasage à la sortie d'un interféromètre d'aire non nulle, lorsque le dispositif est en rotation. On montre que l'effet Sagnac appliqué aux ondes de matière associées à des atomes de césium par exemple, est 1011 fois plus sensible que lorsqu'il est appliqué aux ondes lumineuses. La principale difficulté du dispositif est de séparer et de recombiner de façon cohérente les ondes atomiques. Dans notre dispositif, ceci est réalisé dans la zone d'interaction, grâce à des transitions à deux photons appelées transitions Raman stimulées. C'est l'impulsion des deux photons qui, une fois transférée à l'atome au cours de la transition, va provoquer la séparation angulaire des deux paquets d'ondes atomiques. La réalisation du dispositif s'appuie sur un grand nombre de nouvelles solutions techniques qui ont été validées au cours de la thèse. L'un des soucis principal a été de réaliser un appareil compact et suffisamment insensible aux paramètres extérieurs (champ magnétique, température, ?) pour qu'il puisse être transportable. Notre source atomique est une source à atomes refroidis par lasers, permettant ainsi d'avoir une zone d'interaction réduite tout en conservant un très bon niveau de performance. L'appareil est également sensible aux accélérations ; une technique de double jets atomiques contra-propageant a donc été mise en ?uvre pour discriminer les déphasages liés à la rotation et à l'accélération.

Abstract

This work reports on an optically-pumped vertical external-cavity surface­emitting laser emitting around 852 nm dedicated to atomic physics experiments with cold Cs atoms. The design of the semiconductor active structure has been optimized to provide a low threshold. A low-power diode-pumped compact prototype has been developed with improved stability. With this setup, we obtained a 17-mW single frequency emission exhibiting large tunability around the Cesium D2 line. The laser linewidth has been measured to less than 500 kHz on a 10 ms time.
