1. A detection system for use during irradiation of an interaction region of a structure with laser light, the structure comprising embedded material, the detection system comprising:

  • a focusing lens positioned to receive light emitted from the interaction region;

    an optical fiber optically coupled to the focusing lens to receive light from the focusing lens; and

    a spectrometer optically coupled to the optical fiber to receive light from the optical fiber, the spectrometer adapted for analysis of the light for indications of the embedded material within the interaction region.
