A laser of sufficient intensity traveling through air will - by itself - engineer a narrow channel over which light will propagate for tens or even hundreds of meters. Such filaments of laser light were first created at the end of the twentieth century, and investigators are now beginning to explore new applications for them.

Light Filaments: Structures, challenges and applications brings together exciting results from this area of research. With the development of high repetition rate sources, new aspects of waveguiding are emerging based on the hydrodynamic perturbation...
