Full textMulti-conjugate Adaptive Optics (MCAO) has been suggested in astronomy to increase the correction field of adaptive optics. The effects of atmospheric turbulence are stronger in case of near to ground observations: the correction field is smaller and diffractive effects of the propagation can no longer be neglected. The main purpose of this work is to study MCAO performances and limitations when the diffractive effects of the propagation are taken into account. We have considered an ideal configuration of two layers and two exactly conjugated dynamical mirrors. We show that MCAO may provide a good correction even if perturbations are strong. We observe that the limitation to a perfect correction comes from pupil truncation effects. They cause intensity fluctuations in the conjugated plane of the pupil. We propose a model of the point spread function which takes into account those effects. Concerning intensity fluctuations, we demonstrate that they can strongly affect wavefront measurement and therefore jeopardise MCAO systems operation. Finally, in the framework of the small perturbations approximation, we have expressed analytically the correlations between Shack-Hartmann data (slopes and intensities) as functions of the Cn² profile. This formalism is used to study anisoplanatism effects on wavefront measurement with a Shack-Hartmann operating on extended sources. We also demonstrate that it can be used to recover the Cn² profile by data inversion

Full textThis thesis deals with nonlinear propagation of partially coherent waves in optical fibers. We focus our attention on systems of random waves that are well described by the integrable one dimensional nonlinear Schrödinger equation. We study both experimentally and numerically the statistical evolution of power fluctuations of random waves both in normal and in anomalous dispersion regimes. In order to measure statistics of the power fluctuations of partially coherent optical waves with typical time scales in the range of picosecond, we have performed an asynchronous optical sampling method. Our experiments show that nonlinear propagation strongly influences the statistics of wave systems by producing deviations from the normal distribution. The probability of occurrence of extreme events is significantly enhanced in the focusing regime whereas it is strongly reduced in the defocucing regime. Our numerical simulations of the one-dimensional nonlinear Schrödinger equation reproduce experimental results in a quantitative way. Moreover, our results provide evidence of the emergence of coherent structures embedded in the random fluctuations. In the focusing regime, we observe coherent structures similar to solitons on finite background that are now considered as prototypes of rogue waves. From our work about nonlinear propagation of random waves in systems described by nearly-integrable equations, we hope to contribute to the development of the field of integrable turbulence

Full textAn optical link based on a multiplex of wavelengths at 1.55µm is foreseen to be a valuable alternative to the conventional radio-frequencies for the feeder link of the next-generation of high throughput geostationary satellite. Considering the limited power of lasers envisioned for feeder links, the beam divergence has to be dramatically reduced. Consequently, the beam pointing becomes a key issue. During its propagation between the ground station and a geostationary satellite, the optical beam is deflected and possibly distorted by atmospheric turbulence. It induces strong fluctuations of the detected telecom signal, thus reducing the capacity. A steering mirror using a measurement from a beam coming from the satellite is used to pre-compensate the deflection. Because of the point-ahead angle between the downlink and the uplink, the turbulence effects experienced by both beams are slightly different, inducing an error in the correction. The performance criteria is the minimum detectable irradiance 95% of the time. A fast model, named WPLOT, taking into account pointing errors and their temporal evolution, is proposed to evaluate the minimum irradiance as a function of the ground station parameters and quality of the correction. The model’s results are compared to those obtained with a more physical but requiring more computation power: TURANDOT. A sensitivity study has been realized and led to a sizing of a ground station. The model also enables the generation of time series in order to optimize the forward error correction codes in order to be compliant with the targeted capacity (1Terabit/s by 2025)

Full textOptical turbulence and its impact on measured images is a well-known phenomenon in astronomy. Models based on the Kolmogorov theory, elaborated for a dynamical turbulence description, and methods, such as Adaptive Optics, were both developed so as to understand and correct the degradations caused by this turbulence. Analysis of the same phenomenon in indoor situation was however less investigated. The local air volume is nonetheless prone to optical perturbations sources which could have non negligible impacts on the measurements of instruments installed at proximity. This document introduces a first approach of indoor optical turbulence characterization. After the introduction of the studied phenomenon and the mathematical tools employed, this thesis present optical turbulence characterizations inside Thales Alenia Space clean rooms used for optical instrument integration and testing. Analyses inside telescope domes are also shown in this document. All the results were obtained using the INTENSE instrument which was developed during the thesis for optical turbulence characterizations using angle of arrival fluctuations of laser beams. In anticipation for future ameliorations of optical turbulence analysis methods, a chapter of this thesis is dedicated to the work made on a turbulence energy profile extraction and its application on the INTENSE instrument. Conclusions and perspectives of the work made during this thesis are presented at the end of the document
Sudrie, Lionel. "Propagation non-linéaire des impulsions laser femtosecondes dans la silice." Paris 11, 2002. https://hal-ensta.archives-ouvertes.fr/tel-01188199.
Full textThe subject of this thesis is the study of the propagation of femtosecond laser pulses in transparent solids. The short duration of these pulses (a few 10^-15 to a few 10^-13 s) supplies high light intensities with modest energies. When they traverse a transparent medium, theses strong laser intensities induce important nonlinearities which affect the pulse propagation. These nonlinearities can lead to a self-guided propagation with high intensities on long distances. This propagation is called laser filamentation. By focusing pulse of 2 mJ, 160 fs and with 800 nm as central wavelength, I have induced a laser filamentation in a 2 cm thick fused silica sample. The experimental study of this nonlinear propagation is the first precise and complete characterization of a filament in a transparent solid medium. Comparison between experimental and numerical results given by numerical code permits to show that laser filamentation can take place in solid, media in the same way as in gases. Equilibrium between self-focusing due to Kerr effect and defocusing by the plasma is the origin of filamentation. Defocusing limits the laser intensity and avoids sample damaging. This close relation between propagation and damaging led me to consider more strongly focused pulses propagation inside fused silica. This type of propagation leads to high electronic densities that induce irreversible damages. Comparison between numerical and experimental results permits to precise the conditions for damages appearance while giving experimentally inaccessible physical quantities. I have also observed in fused silica a new type of modifications with a strong birefringence. As an application I have made optical elements like waveguides and diffraction gratings
