摘要: Ultrafast laser filament induced breakdown spectroscopy is a very promising method for remote material detection. We present characteristics of plasmas generated in metal target by filaments air. Our measurements show that the temperature ablation plasma clamped along channel due to intensity clamping filament. Nevertheless, significant changes radiation are noticeable, and this essentially variation number density emitting atoms. The results also explain near absence ion emission but strong atomic neutral from plumes produced during fs LIBS
