Claim 12:
13. A method for operating an actively Q-switched laser induced breakdown spectroscopy (LIBS) probe, the method comprising:
starting a topside control unit connected to the LIBS probe by an optical fiber, wherein the LIBS probe is positioned downhole;
determining whether to use a previously loaded program;
determining whether to use a previously used pump level;
setting up a spectrometer to read information returned by the LIBS probe through the optical fiber;
determining pump frequency and duration;
pulse pumping to the LIBS probe;
generating high energy pulses at the LIBS probe, the pulses producing high energy plasma;
returning optical data on the higher energy plasma to the spectrometer through the optical fiber; and
producing a measurement.
