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 …

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 …

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 …

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 …

We demonstrate a harmonic-seeded switchable multiwavelength laser in air driven by
intense midinfrared femtosecond laser pulses, in which population inversion occurs at an …

This is a review of some recent development in femtosecond filamentation science with
emphasis on our collective work. Previously reviewed work in the field will not be discussed …

Focus Serial: Frontiers of Nonlinear Optics We review the properties and applications of
ultrashort laser pulses in the atmosphere, with a particular focus on filamentation …

Ultrashort, high-power laser pulses propagating vertically in the atmosphere have been
observed over more than 20 km using an imaging 2-m astronomical telescope. This direct …

The state of the art of investigations on filamentation of a high-power femtosecond laser
radiation in transparent media is reviewed. The physical picture of this phenomenon is …
