Paper Abstract

Studies were performed using self-channeled femtosecond laser pulses (filaments) interacting with various materials at a distance of 30 meters. Using time resolved optical shadowgraphy, the filament interaction with the target is observed. Shockwaves in both the target and the surrounding atmosphere are observed and their velocities measured. Estimations of the shockwave energy are made from these observations. In transparent targets, optical coupling into the target material is observed. This coupling results in optical damage lines in the material. Results of the filament interactions will be discussed along with supporting modeling.
