Abstract

Super-resolutive 3D tracking, such as PSF engineering or evanescent field imaging has long been used to track microparticles and to enhance the throughput of single molecules force spectroscopic measurements. However, current methods present two drawbacks. First, they lack precision compared with optical tweezers or AFM. Second, the dependence of their signal upon the position is complex creating the need for a time-consuming calibration step. Here, we introduce a new optical technique that circumvents both issues and allows for a simple, versatile and efficient 3D tracking of diluted particles while offering a sub-nanometer frame-to-frame precision in all three spatial directions. The principle is to combine stereoscopy and interferometry, such that the z (axial) position is measured through the distance between two interferometric fringe patterns. The linearity of this stereoscopy technique alleviates the need for lookup tables while the structured interferometric pattern enhances precision. On the other hand, the extended spatial footprint of this PSF maximizes the number of photons detected per frame without the need of fancy cameras, nor the need for complex hardware. Hence, thanks to its simplicity and versatility, we believe that SDI (Stereo Darkfield Interferometry) technology has the potential to significantly enhance the spreading of 3D tracking. We demonstrate the efficiency of this technique on various single-molecule measurements thanks to magnetic tweezers. In particular we demonstrate the precise quantification of two-state dynamics involving axial steps as short as 1 nm. We then show that SDI can be directly embedded in a commercial objective providing a means to track multiple single cells in 3D ., Comment: 15 pages main text, 3 main figures, 28 pages supplementary, 35 supplementary figures 2020/08/13 : corrected typos, merged parts 3.1 and 3.3 for more clarity

Abstract

Mid-infrared femtosecond lasers have recently provided a new tool to study complex ultrafast dynamics, especially in biological systems such as hemeproteins. Using these lasers, two kind of powerful experiments can be planned. The first type contains optimal control experiments, in which the principle is to find the optimal shape of a pulse in order to reach one desired final state. This approach requires a way to produce an arbitrary shape of pulses, so in a first part we have worked on a new kind of linear programmable acousto-optic pulse-shaper called Mid-infrared Dazzler, which is produced by the company FASLITE. For this sake, we have implemented a new method to measure weak mid-infrared pulses with complex shapes, based on the homodyne detection of a replica of the mid-infrared field into the visible domain. Then, we have produced and measured shaped pulses which exhibit complex shapes like pi-steps in the spectral phase. This demonstrates the ability of the Dazzler to be used in optimal control experiments with hemeproteins. The second type of experiments contain the multidimensional coherent spectroscopy experiments, which are powerful tools to probe ultrafast dynamics since the principle is to measure the complete non-linear response function, which permits to disentangle the different microscopic informations. We have finalized the building of an innovative two-dimensional spectrometer, which exhibits a simple geometry, an excellent spectral resolution in both axes, an iterative and very precise self-calibration method, and a simple and efficient trick to remove the signal from scattering. Our first measurements of the Frequency-frequency correlation function of the CO vibration bound to Hemoglobin shows a promising agreement with recent progress in the modelization of ultrafast fluctuations., La mise au point des lasers femtosecondes, en particulier dans le moyen-infrarouge, a ouvert une voie d’étude des systèmes biologiques, où les couplages et les fluctuations impliquent des déphasages ultra-rapides. Ce travail participe à l’élaboration d’outils pour l’étude de systèmes vibrationnels, ici la carboxy-hémoglobine HbCO. L’approche du contrôle optimal, d’une part, détermine empiriquement le profil optimal d’une impulsion en vue d’un objectif, nécessitant la programmation d’impulsions de formes arbitraires. Nous avons étudié un prototype d’une technologie acousto-optique de façonnage d’impulsions infrarouges, le Dazzler, conçu par la société FASTLITE. Pour cela, une méthode adaptée de mesure du champ, effectuant la mesure homodyne d’une réplique de l’impulsion dans le domaine visible, a été mise au point. Puis, la production et la mesure d’impulsions infrarouges de formes complexes comprenant un saut de phase spectrale, ont été réalisées, montrant l’adéquation du Dazzler pour des expériences de contrôle cohérent dans les hémoprotéines. D’autre part, la spectroscopie multidimensionnelle mesure la réponse non-linéaire d’un échantillon, constituant un outil puissant d’étude de la surface de potentiel. Un spectromètre bidimensionnel a donc été finalisé, qui combine une géométrie simplifiée, une excellente résolution, une procédure d’auto-calibration itérative et précise, et une solution simple pour éliminer la principale source de bruit. Des mesures de la fonction de corrélation à deux temps de la fréquence de résonance du CO ont enfin été comparées à des résultats préliminaires issus d’avancées théoriques récentes, montrant un accord prometteur pour leur validation.

17. Impact of Pulse Polarization on Coherent Vibrational Ladder Climbing Signals

Author

Nuernberger, Patrick, Vieille, Thibault, Ventalon, Cathie, and Joffre, Manuel

Abstract

We report a theoretical study that elaborates the influence of the polarization state of both the pump and the probe pulse in ultrafast coherent vibrational ladder climbing experiments in the mid-infrared. Whereas a subensemble in a randomly oriented sample of molecules is excited by the pump pulse in this multiphoton process, further inhomogeneities such as the spatial profile of the laser beams, the longitudinal attenuation in the sample, and the probe beam polarization have to be taken into account. Analytical expressions for a density function describing the number of molecules that are exposed to an effective pump intensity are introduced, and the variation of the population distribution and the actual transient absorption signal in dependence on the polarization-state combinations for pump and probe pulse are discussed in detail. In simulations on the model system carboxy-hemoglobin, it is demonstrated that the polarization states play important roles both for exciting a certain population distribution and for actually observing it. In particular, it will be discussed under which conditions experimental data indicates a population inversion.

21. Calibration of an adaptive microscope using phase diversity

Author

Débarre, Delphine, Vieille, Thibault, Facomprez, Aurélie, Mahou, Pierre, and Beaurepaire, Emmanuel

Abstract

Accurate control over the phase and amplitude modulation in an adaptive microscope is essential to the quality of aberration correction that can be achieved. In this paper we present a robust and compact method for characterising such amplitude and phase modulation in the pupil plane of the focussing objective. This method, based on phase diversity, permits calibrating the microscope as a whole and thus avoids errors in the alignment of the wavefront shaping device after calibration and the resulting imprecision in the induced modulation: by acquiring three 2D images of the point spread function at different distances from the focal plane, we show that the electric field distribution at the pupil plane can be retrieved using an iterative algorithm. We have applied this technique to the characterisation of the phase modulation induced by a deformable mirror when conjugated with the entrance pupil of different objectives, which permits accurate evaluation of the performance of the mirror for subsequent aberration correction.
