1. An in-situ laser plasma spectroscopy (LPS) apparatus, comprising:

  • an enclosure for housing a laser energy source;

    a main fiber connected to said enclosure at a first end of said main fiber, and connected to a probe at a second end of said main fiber, said main fiber configured for transmitting input laser energy from said laser energy source to a target and for transmitting laser induced plasma emission signals back from said target; and

    said probe being moveable with respect to said target and having a single focal lens, said input laser energy from said main fiber being focused to said target by movement of said probe for directing said laser induced plasma emission signals from said target to said main fiber.
