This book is focused on the nonlinear theoretical and mathematical problems associated with ultrafast intense laser pulse propagation in gases and in particular, in air. With the aim of understanding the physics of filamentation in gases, solids, the atmosphere, and even biological tissue, specialists...
We report the development of a model written in the COMSOL multi-physics environment to simulate the onset and shortrange propagation of laser filaments in standard atmospheres at sea-level and 10 km altitude. We show excellent agreement with analytical and open-source experimental data for the ...

We numerically simulated the air-flow motion in a diffusion cloud chamber induced by femtosecond laser filaments for different chopping rates. A two dimensional model was employed, where the laser filaments were treated as a heat flux source. The simulated patterns of flow fields and maximum velocit...
Characteristics of energy deposition during filamentation are numerically investigated to understand the formation of different mass of snow with femtosecond laser pulses in a cloud chamber. The results show that the evolution of maximum airflow velocity and mass of snow is closely related to the ...
Femtosecond Laser Filamentation gives a comprehensive review of the physics of propagation of intense femtosecond laser pulses in optical media (principally air) and the applications and challenges of this new technique. This book presents the modern understanding of the physics of femtosecond laser pulse...
In this paper, we experimentally investigate supercontinuum generation via collinear two-color filamentation in sapphire crystal, by launching two femtosecond pulses at fundamental (1030 nm) and second harmonic (515 nm) wavelengths from an amplified Yb:KGW laser. By changing the time delay between ...
Laser theoryOptical refractionIn this work, we focused on the resonant cavity effect of the air plasma, formed during femtosecond laser filamentation, on the near- and far-field profiles of the generated terahertz (THz) radiation. Via the method of ray tracing, it has been demonstrated that ...
