Single-Beam Stimulated Raman Scattering for sub-Microgram Standoff Detection of Explosives

Open Access Open Access

Abstract

A 12fs laser pulse is used to both excite vibrational modes and amplify Raman scattering. Selectivity is accomplished by temporal shaping. Imaging of microcrystals on different substrates from several meters becomes possible.
