Stand-Off Detection of Organic Samples Using Filament-Induced Breakdown Spectroscopy

摘要

As an alternative to focusing nanosecond pulses for stand-off LIBS detection of energetic materials, we use self-channeled femtosecond pulses from a Ti:Sapphire laser to produce filaments at 12 meters and create a plasma on copper, graphite and polyisobutylene film. We show the possibilities of this Laser-Induced Breakdown Spectroscopy configuration for thin organic sample detection on a surface at a distance.
