On the interaction of femtosecond laser pulses with layered dielectric materials
Materials properties are strictly dependent on their microstructure. The internal symmetries and the disposition of the constituting atoms of a material, which depend on its crystallographic structure, greatly affect its response to mechanical, electromagn ...
EPFL2023Interactions of Cavitation Bubbles with Deformable Interfaces
Cavitation is a topic that has long been of interest due to the large and growing range of applications associated with it. This is mainly because the collapse of cavitation bubbles releases a considerable amount of energy into the surrounding environment. ...
EPFL2023Effect of femtosecond laser-induced high pressure on fused silica polymorphism
High-pressure studies in silica are of great interest to earth and planetary sciences. Highpressure phases are rarely found in nature as a result of shock events like meteorite impacts orvolcanic events in nature. Recreating these phases remains a challeng ...
EPFL2022Degradation study on molecules released from laser-based jet injector
Christophe Moser, Jan Krizek, Barbora Lavickova
Development of needle-free methods to administer injectable therapeutics has been researched for a few decades. We focused our attention on a laser-based jet injection technique where the liquid-jet actuation mechanism is based on optical cavitation. This ...
2021Energetics and mixing of thermally driven flows in Hele-Shaw cells
Thermally driven flows in fractures play a key role in enhancing the heat transfer and fluid mixing across the Earth’s lithosphere. Yet the energy pathways in such confined environments have not been characterised. Building on Letelier et al. (J. Fluid Mec ...
2021Design of a compliant load cell with adjustable stiffness
Charles Baur, Lennart Rubbert, Michal Stanislaw Smreczak
Manipulation at the sub-micron scale often requires force-sensing capabilities of milli-to nanonewton forces. This article presents a novel design of a compliant load cell with mechanically adjustable stiffness. The system enables adapting force sensitivit ...
ELSEVIER SCIENCE INC2021Free Boundary Regularity for Almost Every Solution to the Signorini Problem
We investigate the regularity of the free boundary for the Signorini problem in Rn+1. It is known that regular points are (n−1)-dimensional and C∞. However, even for C∞ obstacles φ, the set of non-regular (or degenerate) points could be very large—e.g. wit ...
2021A tunable femtosecond fiber laser source for multiphoton emission microscopy
Pierre-Marc Jean Marie Dansette
Second harmonic generation microscopy is used to image interfaces or non-centrosymmetric structures and molecules. Two-photon fluorescence microscopy can image molecules within cells without using markers. Thus those technics have lead to advances in our u ...
EPFL2021Instability of a thin viscous film flowing under an inclined substrate: the emergence and stability of rivulets
François Gallaire, Gioele Mariano Nicolò Balestra, Pier Giuseppe Ledda, Gaëtan Pierre Clément Lerisson
We study the pattern formation of a thin film flowing under an inclined planar substrate. The phenomenon is studied in the context of the Rayleigh-Taylor instability using the lubrication equation. Inspired by experimental observations, we numerically stud ...
2020Generating optical pulses via a soliton state of an optical microresonator coupled with a chip based semiconductor laser
Tobias Kippenberg, Hairun Guo, Arslan Sajid Raja
A light pulse source (100), being adapted for generating repetitive optical pulses (1), comprises a continuous wave cw laser device (10) being arranged for providing cw laser light (2), an optical waveguide (20) being optically coupled with the cw laser de ...
