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 …

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 …

The current research into solitons and their use in fiber optic communications is very
important to the future of communications. Since the advent of computer networking and …

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

The purpose of this article is to provide practical introduction into numerical modeling of
ultrashort optical pulses in extreme nonlinear regimes. The theoretic background section …

Spatial-and time-domain versions of the unidirectional pulse propagation equation (UPPE)
are derived and compared from the point of view of their practical application in simulations …

This book attempts to give a discussion of the physics and current and potential applications
of the self-focusing of an intense femtosecond laser pulse in a transparent medium …

Femtosecond laser pulses appear as an emerging and promising tool for processing wide
bandgap dielectric materials for a variety of applications. This article aims to provide an …

We report an investigation of white-light continuum generation and self-focusing by 140-fs
Ti: sapphire laser pulses in extended transparent media. It is found that continuum …

When a powerful femtosecond laser pulse propagates in an optical medium, self-focusing
occurs. Normally, it is the most powerful part (slice) of the pulse that self-focuses first during …
