Texte intégralIn this work we explored the ultrafast dynamics of photo-excited hot electrons in plasmonic structures. The particular interest of this field resides on the fact surface plasmons (SP), because of their unrivaled temporal and spatial characteristics, provide a technological route for ultrafast information processes at the nanoscale. In this context, this manuscript provides a comprehension and the harnessing of one of the major limitation of the SP-based technologies : absorption losses by Joule heating. We exploit the fact that the mechanism of plasmon absorption in metals is followed by generation of hot electrons at femtosecond time scale, thus losses can be seen as a plasmon-to-hot-electron energy conversion. This energy conversion is measured with femtosecond pump-probe technique. Femtosecond SP pulses are launched and probed over hundred femtoseconds through the permittivity variations induced by the hot-electron gas and which accompany the SP propagation. The measured electron temperature profile is therefore an image of plasmon power density distribution (absorption) not broadened spatially and temporally by energy carrier diffusion. As an important result we demonstrated the capability to link the electronic temperature measurement to the plasmonic absorption, revealing an anomalous light absorption for a sub- slit surroundings, in quantitative agreement with predictions of the power density distribution. In a second part we studied plasmon losses and their characteristics when they propagate on semi-infinite metal film. We determined the electronic thermal wave velocity and damping. In the last part we used a focusing taper-structure to adiabatically guide and focus the plasmon at the apex. Was demonstrated the generation of a nanoscale hot spot and put in evidence a delayed electron heating at the taper apex. Perspectives and the remaining open questions are also discussed

The optical resolution of microscopy is limited by the wave-like characteristic of the light. There are many recent advances in overcoming this diffraction limited resolution, but mostly focused on fluorescent imaging. Furthermore, there are few non-fluorescence wide-field super-resolution techniques that can fully utilize the applicable laser power to optimize imaging speed. Structured illumination microscopy is a super-resolution method that relies on patterned excitation. This thesis has presented novel applications of structured illumination microscopy to surface plasmon resonance fluorescence and pump-probe scattering imaging. First, structured illumination microscopy was introduced to surface plasmon resonance fluorescence imaging for high signal-to-noise and high resolution. Secondly, a theoretical framework for three-dimensional wide-field pump-probe structured illumination microscopy has been developed to increase the lateral resolution and enable depth sectioning. Further, structured illumination wide-field photothermal digital phase microscopy is proposed as a high throughput, high sensitivity super-resolution imaging tool to diagnose ovarian cancer. Finally, I have derived the exact analytical solution to the heat conduction problem in which a sphere absorbs temporally modulated laser beam for photothermal microscopy. The proposed method also has a great potential to be applied to other pump-probe modalities such as transient absorption and stimulated Raman scattering.

Texte intégralUltra-intense femtosecond lasers are widely used for nano and micro-material processing. Explaining the laser-matter interaction is needed to control the processing. In this context, non-diffracting beams, such as Bessel beams, provided substantial advantages regarding the stability of the non-linear propagation within dielectrics. They allowed the generation of extremely high aspect ratio nanovoids. However, conventional models describing Bessel-dielectric interaction fail to explain experimental observations. Therefore, this thesis aims to develop a set of techniques to retrieve the parameters of laser-generated plasmas. The first part develops an approach to shape the polarization of the Bessel beam along its propagation based on spatially-varying waveplates. The second part of this work is dedicated to the imaging of the interaction between the plasma generated by the onset of the pulse and the trailing part inside sapphire. We confirmed a generation of nano-plasma with a density exceeding the critical density, and a diameter of typically 200 nm. Then, the third part of this work focuses on imaging the plasma using a pump-probe approach. This new concept is based on shaping the probe as a higher-order Bessel beam. The plasma parameters are extracted from a set of measurements of reflectivity in amplitude and phase for different orders and angles of the probe pulse

Texte intégralIn this dissertation, we develop pump probe spectroscopy as a method to differentiate different chemical varieties of melanin, a common biopigment, and exploit these differences to improve the accuracy of melanoma diagnosis. This method gives insight into the chemical makeup and secondary structure of melanins. Pump probe spectroscopy is implemented in a scanning laser microscope as a form of multiphoton imaging, where it is used to image biopsies of human pigmented cutaneous lesions. Melanoma diagnosis is clinically challenging: the accuracy of visual inspection by dermatologists is highly variable and heavily weighted toward false positives. Even the current gold standard of biopsy results in varying diagnoses among pathologists. Using pump probe imaging, significant chemical and morphological changes were found between melanoma and melanocytic nevi, including increased eumelanin content, chemical heterogeneity and general pigmentation. Signal processing methods revealed further differences between melanoma and melanocytic nevi on the cellular scale. Pump probe imaging directly in H&E stained biopsy samples allows integration of this technique with existing histopathology protocols. High resolution imaging found chemical heterogeneity of melanin within pigmented cells. We show that oxyhemoglobin and deoxyhemoglobin may also be differentiated by pump probe imaging. Epi mode imaging of eumelanin, pheomelanin and microvasculature is demonstrated in vivo in human xenograft mouse models of melanoma.
