This paper introduces and discusses the main aspects of ultrashort laser pulse filamentation
in various transparent media such as air (gases), transparent solids and liquids. The …

Soon after the invention of the pulsed ruby laser by Maiman in 1960, investigators were
eager to examine the potential of pulsed laser radiation for medical applications. It was …

Modern laser sources nowadays deliver ultrashort light pulses reaching few cycles in
duration and peak powers exceeding several terawatt (TW). When such pulses propagate …

Most long-path remote spectroscopic studies of the atmosphere rely on ambient light or
narrow-band lasers. High-power femtosecond laser pulses have been found to propagate in …

Intense, well-controlled light pulses with only a few optical cycles start to play a crucial role
in many fields of physics, such as attosecond science. We present an extremely simple and …

We report long-range self-channeling in air of multiterawatt femtosecond laser pulses with
large negative initial chirps. The peak intensity in the light channels is at least one order of …

The filamentation of femtosecond light pulses in air is numerically and experimentally
investigated for beam powers reaching several TW. Beam propagation is shown to be driven …

Intense, ultrashort laser pulses propagating in the atmosphere have been observed to emit
sub-THz electromagnetic pulses (EMPS). The purpose of this paper is to analyze EMP …

We investigated the spectral behavior of a white-light continuum generated in air by 2-TW
femtosecond laser pulses at 800 nm. The spectrum extends at least from 300 nm to 4.5 µm …

We show that it is possible to organize regular filamentation patterns in air by imposing
either strong field gradients or phase distortions in the input-beam profile of an intense …
