1. A system for detecting a signal field from a sample volume, said system comprising:

  • a source system for providing a first electromagnetic field at a first frequency and a second electromagnetic field at a second frequency that is different from the first frequency; and

    an optical fiber system including at least one optical fiber for guiding said first and second electromagnetic fields to the sample volume to generate coherent radiation characteristic of molecular vibrations by non-linear interaction of the first and second fields with the sample volume, for receiving the signal field resulting from the coherent radiation, and for guiding the signal field to a detector.
