ABSTRACT:
A light source produces a pump wave that is used to pump a parametric device. The parametric device is configured at or near its degeneracy point and produces a broadband output. The broadband output is directed to a remote location where chemical agents may be located. The broadband output may be transmitted through or scattered from the remote location and chemical agents located at the remote location may absorb portions of the broadband output. The broadband output may be collected and dispersed to produce channels or sub-bands that are detected by a detector array. The detector array may multiplex the intensities of the sub-bands and produce an absorption spectrum. The absorption spectrum may be compared to a library of known chemical agents and the presence of a chemical agent at the remote location can be determined in or near real time.
