1. A method to analyze media for composition and authentication of a source of unknown media comprising the steps of:

  • exposing a sample of unknown media simultaneously to multiple wavelengths from multiple laser sources;

    reading a Raman spectra of the sample of the unknown media through a variety of detectors each with a specific wavelength detection region using Raman spectroscopy, wherein the Raman spectra comprises at least one Stokes component and/or at least one Anti-Stokes component; and

    manipulating mathematically at least one of the Stokes component and/or at least one of the Anti-Stokes component.
