This book is a partial summary of the novel approach pushed forth by the authors and their collaborators in the context of ultrashort laser pulse filamentation. This approach is based on the reinterpretation of filamentation in terms of the spontaneous formation of non–diffractive and non–dispersive wave–packets, known as a X Waves or, more generically, as conical waves. This text is intended as a relatively simple guide into the basics of this model and is therefore adapted to readers at all levels. The first two chapters are devoted to an overview of third–order nonlinear optical effects with particular relevance given to filamentation, and to a general overview of conical waves and their properties. The following two chapters describe in detail the experimental diagnostic tools necessary for characterizing filaments and conical waves and the details of the numerical code based on the Nonlinear Schrödinger equation used by the authors. The last two chapters are dedicated to the discussion of the X Wave model for filamentation and its application to “nonlinear filamentation optics”.Daniele Faccio, is currently researcher (assistant Professor) at the University of Insubria, Como, Italy, and has worked in both University and industrial research institutions on optoelectronic devices for modern optical telecommunication systems.Arnaud Couairon is recognized for his contribution to the physics of ultrashort laser pulse filamentation and for the development of an efficient numerical code based on the Nonlinear Schrödinger equation and used by many research groups world-wide.Paolo Di Trapani is an expert in optical parametric processes, solitons and space–time spontaneous localization phenomena in the ultra–short pulse regime. He has also recently started a campaign of promotion of physics to the general public by a traveling exhibition which proposes the spectacular indoor reconstruction of optical atmospheric phenomena.The authors are currently collaborating together within the framework of an extended international collaboration, the Virtual Institute for Nonlinear Optics (VINO, http://www.vino– The main topic of this collaboration is the study of the spontaneous transformation of ultrashort laser pulses into stationary conical waves with particular emphasis on novel technological applications.
