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 …

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 …

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 …

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 …

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 …

Femtosecond laser filamentation is a unique nonlinear optical phenomenon when high-
power ultrafast laser propagation in all transparent optical media. During filamentation in the …

We report a simple experiment to directly determine the critical power for self-focusing in air
by measuring the focal shift of the focused femtosecond Ti: sapphire laser pulses. The …

Abstract 2012 marked the 50th anniversary of the first published prediction of the self-
focusing phenomenon in light beams. The recent revived interest in the subject is due to …

Powerful femtosecond laser pulses propagating in transparent materials result in the
formation of self-guided structures called filaments. Such filamentation in air can be …

Recent studies have demonstrated that femtosecond laser pulses have high potential in
application to environmental science. Because of the properties of ultrafast, broadband and …
