Femtosecond laser filamentation and applications
, 2021 International audienceFemtosecond filamentation is a spectacular phenomenon whereby a short laser pulse propagates nonlinearly through a transparent medium allowing high peak light intensities to be transferred over distances far exceeding the beam ...

Multiple filamentation Ti:Sapphire-laser pulses in water [PDF]
, 2020 The results of experimental studies of the spatial characteristics of multiple filamentation terawatt femtosecond Ti:Salaser in water are presented. With an increase in initial power laser pulses increases the number of filaments, the length of the field

Polarization-Sensitive Nonlinear Optical Interaction of Ultrashort Laser Pulses with HPHT Diamond
Photonics, 2023 The filamentation of focused 300 fs laser pulses with variable polarization azimuth in bulk of synthetic HPHT diamond demonstrates the possibility of polarization-dependent bandgap control for crystal dielectric photoexcitation. This directly affects the

Lighting the Universe with Filaments [PDF]
Science, 2007 The first stars in the universe form when chemically pristine gas heats as it falls into dark-matter potential wells, cools radiatively because of the formation of molecular hydrogen, and becomes self-gravitating. Using supercomputer simulations, we demonstrated that the stars' properties depend critically on the currently unknown nature ...

Microbiology Spectrum, 2016 ABSTRACTFilamentous mycoses are often associated with significant morbidity and mortality. Prompt diagnosis and aggressive treatment are essential for good clinical outcomes in immunocompromised patients. The host immune response plays an essential role in determining the course of exposure to potential fungal pathogens.

Semiflexible Filamentous Composites [PDF]
Physical Review Letters, 2010 Inspired by the ubiquity of composite filamentous networks in nature we investigate models of biopolymer networks that consist of interconnected floppy and stiff filaments. Numerical simulations carried out in three dimensions allow us to explore the microscopic partitioning of stresses and strains between the stiff and floppy fractions c_s and c_f ...

Filamentation of Femtosecond Vector Beams
, 2023 We numerically study the filamentation of femtosecond vector beams with spatially varying polarization profiles in air. The vector beams include azimuthal, radial, and spiral cylindrical vector beams (CVBs), as well as low-order full Poincar\'e beams ...
