LIBS/RAMAN

GOAL: Creation of an integrated instrument capable of LIBS and Raman spectroscopy of surfaces at sub-100 μm spot size with laser delivery and spectra collection via optical fibers.  LIBS utilizes a highly focused laser pulse to ablate a small amount of surface material and generate a plasma ball.  During cooling of the plasma, atomic emission spectra are emitted, providing qualitative and quantitative information about the atomic composition of the material.  Raman spectroscopy here makes use of the same laser at a lower, non-destructive power.  The inelastic scatter of the laser light interacting with vibrational and rotational energy modes of molecules produces distinctive spectral signatures, providing information about the molecular composition of the surface.
