Claim Text:
1. A system for detecting materials comprising: (a) at least one laser configured to output light in the near infrared (IR) spectrum, the wavelength of the output laser light corresponding to a frequency associated with at least one vibrational overtone absorption transition, at least one combination band absorption transition, or a combination thereof, of a sample comprised of one or more materials so as to be absorbed and to excite the sample; (b) a detector configured to detect an excited physical phenomenon of the sample in response to absorption of the output laser light at the frequency associated with the at least one vibrational overtone absorption transition, the at least one combination band absorption transition, or the combination thereof; and (c) an analyzer configured to analyze the detected excited physical phenomenon and to identify the one or more materials based on comparison of the detected excited physical phenomenon with known signatures of the one or more materials.
