Self-Channeling of Femtosecond Laser Pulses for Rapid and Efficient Standoff Detection of Energetic Materials

Abstract

Self-channeling properties of high intensity laser pulses are used to extend spectroscopic methods as LIBS to standoff. This work shows the advantages of using selfchanneled femtosecond pulses in Laser-Induced Breakdown Spectroscopy of polymeric micrometer-size thin films in a standoff configuration at 12 meters. We show the possibility of trace analysis on surfaces and the importance of molecular signal as a signature for carbon-based samples.
