Повний текст джерелаThis work is about dual-polarization dual-frequency fibers lasers. The control of the frequency difference of these lasers is a major challenge in microwave photonics. Controlling the beat frequency could allow compact and low-noise sources, in order to develop applications in metrology or telecom. Here, we focus on 1.5 μm sources, in either DFB or DBR configurations, made of Er-doped or co-doped Er:Yb silica fibres. Their beat frequency is about 1 GHz for DFB lasers, and 100 MHz for DBR lasers. This thesis investigates several methods to stabilize the beat note, then to modify the fiber birefringence, to increase the beat frequency. First, an optical phase-locked loop method is used to lock the beat note on a frequency reference. By using the pump diode as an actuator, we have successfully stabilized beat frequencies between 300 MHz and 10 GHz for days. We then study a stabilization method by frequency-shifted optical feedback. A theoretical model based on rate equations model is used and allows to retrieve the experimental observations. We observe different dynamical regimes by locking the beat note on a reference frequency. In the stable area, we reduce the phase noise to −100 dBc/Hz at 1 kHz from the carrier. Next, we have mixed the set-up of the injection-locking to a delay line, in order to effectively stabilize the beat note on itself. Finally, various approaches have been explored to increase the beat frequency of DBR lasers, to the needs of applications. It has been possible to continuously monitor the impact of a UV beam on the fiber birefringence. We also studied a method for reversible modification of the birefringence, exploiting the elasto-optical effect. Regardless of the method used, we observed an increase in the beat frequency from 100 MHz to more than 10 GHz in the best case

Повний текст джерелаLong term stabilised lasers are used in a multitude of metrological applications and are the basis of experimental research in very high resolution spectroscopy. This document describes my thesis work on stabilised Nd:YAG lasers in view of space applications (for fundamental physics experiments and geodesy). All experiments must satisfy criteria of compactness, mechanical stability, robustness and reliability. I will describe the possible references for the long (molecules) and the short (resonators) term time intervals with their principal limitations. The discussion leading to their choice is actually connected to the stabilisation techniques to be adequately implemented (PDH, Tilt-Locking, Modulation transfer). Among the stabilisation techniques, the Pound-Drever-Hall (PDH) technique is now a classic as it produces the best performance in short term, so far. To reduce active components, we have also implemented a DC technique called Tilt-Locking and I will compare with PDH in the case of a monolithic Fabry-Perot reference. Theoretical performances on the long term and quantum efficiencies will be compared for different techniques. The schematic principles of the experiences and the results I have obtained for stabilised lasers on Fabry-Perot and molecular iodine are presented. We calibrated the Fabry-Perot drifts, this allows me to point out analytical and numerical solutions to control the length of this mechanical reference. Finally suggestions for further work will be approached and, in the appendices, details about noise order of magnitudes for LISA, a theoretical overview of gravitational waves as well as different simulations and calculations are presented

Повний текст джерелаLa configuration de l'interféromètre rend le bruit de fréquence du laser négligeable si le laser est asservi en fréquence. La stabilisation de fréquence se fera en deux étages, l'un qui asservit la fréquence sur la longueur d'une cavité courte, le deuxième qui asservit sur les grands bras de l'interféromètre. Le premier étage a été construit. J'ai vérifié que ses performances remplissent les spécifications. La stabilité de fréquence obtenue se révèle être exceptionnelle.

Повний текст джерелаAs part of the LISA mission using interferometry to detect gravitational waves, a frequency pre-stabilization of the lasers is required. The frequency reference currently planned to use is a Fabry-Perot cavity. The choice of this technique is mainly due to the simplicity, compactness and frequency stability performance of such a System. However, this System needs high thermal stability requirements and does not provide information on the absolute value of the laser frequency. It is moreover always advisable in a space project to have an alternative method compatible with the requirements of the mission. Consequently, the work presented in this manuscript describes the use of a hyperfine transition of the di-iodine (I2) molecule as a frequency reference. This method of controlling a Nd: YAG laser, widely used in metrology, has already demonstrated frequency stability performance betterthan those required for the LISA project. Following some preliminary studies, we have adapted such a stabilization System to space constraints. The implemented System presents performances of frequency stability of about 30Hz / V Hz to 10 mHz with an noise increase at lower frequencies. It therefore meets the constraints set by the mission. A System characterization and its main sources of perturbations (related to ambient temperature ~2kHz/K, beams misalignments ~16kHz/mrad,. . . ) is also given in the manuscript. This study has strengthened the attractiveness of locking a Nd: YAG laser on the molecule of di-iodine for a space mission (especially LISA)

Повний текст джерелаThis manuscript details the transfer of an ultra-stable optical frequency reference by means of an optical link and its application to the phase-lock of a mid-infared laser. An optical fiber link allows the ultra-stable transfer of a frequency by using a scheme wich compensates the propagation noise. We extended this system to longer links, and transferred the optical frequency reference simultaneously witn internet data. A cascaded link of 300 km and a simple link of 540 km had been demonstrated with a stability of 10⁻ ¹⁹ at 10⁴ s. Such a link as been used to lock a CO² laser at LPL, emitting at 10 µm, to a frequency reference developed at LNE-SRTE, Observatoire de Paris. This reference is an ultra-stable laser, emitting at 1.54 µm, the frequency of wich is measured against the primary standards of LNE-SYRTE by using a femtosecond laser. This reference is tranferred by an optical link to LPL, in order to stabilize the repetition rate of a second femtosecondlaser and to measure or control the frenquency of a CO² laser. When the CO² laser is locked to a molecular reference (OsO₄), the stability is 4.10⁻¹⁴ at 1s. The performances are even better when the CO² laser is locked directly to the optical reference. Then the laser coulb be used for the experiment of observation of the parity violation in chiral molecules, in progress at LPL. This shows the feasability of high resolution molecular spectroscopy experiments in laboratoratories in wich there is no primary standards
