Claim 7:
8. A laser induced breakdown spectroscopy (LIBS) system comprising:
a topside control system comprising an optical pumping source connected to an optical fiber; and
a downhole LIBS probe comprising:
an adjustable focus lens arrangement connected to the optical fiber;
an actively Q-switched (AQSW) laser connected to the adjustable focus arrangement;
a sample area connected to at least a beam of the laser; and
a spectral emission control connected to at least one of the optical fibers and the optical pumping source;
a selective mirror located between the optical fiber and the actively Q-switched laser which selectively reflects a non-powering wavelength and directs an output to an AQSW control;
the AQSW control selectively activating the AQSW laser based on a non-powering wavelength sent from the optical pumping source, allowing for remote control of the AQSW laser's output, wherein the optical pumping source is part of a topside control system comprising the pumping source, a computer, a trigger, and a spectrometer for receiving information returned through the optical fiber.
