Laser-induced fluorescence of ultrafast laser filament generated plasmas for standoff detection

Not Accessible

Your library or personal account may give you access

Abstract

Ultrafast laser filament produced plasmas are made at a standoff distance of ~ 10 m. The Al emission signal features are enhanced by resonant excitation employing a continuous-wave laser, and laser-induced fluorescence signals are measured. A comparison is made between the standoff signatures of LIBS and LIF emission.
