Last week JPhysB published a Special Issue on the subject of Filamentation.
In their editorial Guest Editors Ruxin Li, Howard Milchberg and Andre Mysyrowicz explain:
Twenty years after its first observation in air, the filamentation of ultrashort optical pulses remains a topic of high fundamental and practical interest. The filamentation process touches on many fields: nonlinear optics, plasma physics, molecular and atomic physics, ultrafast dynamics, hydrodynamics, acoustics, and atmospheric sciences. Filamentation has promising applications, many of them related to the fact that high laser intensities may be transported large distances in the atmosphere or that extended atmospheric modification may be possible.
The issue is available to read here.
