The phenomenon of laser filamentation is believed to be a dynamic balance between the nonlinear Kerr effect and defocusing induced by the generated plasma. The diffraction balanced atmospheric propagation of these self-guided beams and their ability to deliver high intensity at a long distance makes them very attractive for remote sensing and defense applications. New interest in the filamentation of mid- and far-IR lasers, especially for atmospheric applications, could enable applications such as guiding long wavelength electromagnetic waves and lightning and weather control.
The purpose of this feature issue is to present recent advances in all aspects of laser filamentation including experimental results and theoretical models that shed light on the fundamental characteristics of these self-induced waveguides.
