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 rise time of intense radiation determines the maximum field strength atoms can be
exposed to before their polarizability dramatically drops due to the detachment of an outer …

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 …

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 …

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 …

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

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 …

Over the past four years, there has been a surge of activity in the supercontinuum field since
the introduction of various types of microstructure fibers. The main reason for this great …

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 …
