Abstract
A system and a method for detecting the existence of a target substance, the system includes a laser with a broad spectral output and a detector for detecting an absorption spectrum of a laser beam from the laser. The method includes emitting a laser beam into the atmosphere using a laser light with a broad spectral output; measuring the absorption spectrum of said laser beam; comparing the absorption spectrum to known absorption spectrums for target substances using a detector; and detecting the existence of a target substance.
