Claim 0:
1. A laser induced breakdown spectroscopy (LIBS) probe, comprising:
a topside control system comprising a pumping source;
an optical fiber, a pump beam transmitted through the optical fiber, wherein the optical fiber is connected to the topside control system and a downhole sensory system comprising:
a coupler connected to the optical fiber; a first lens, the first lens connected to the coupler, the first lens having a predetermined shape and a first lens coating, the first lens collimating the pump beam;
an actively Q-switched laser, the actively Q-switched laser coupled to a sensor which provides information to a computer that controls a high voltage pulser, the high voltage pulser providing a pulse to the actively Q-switched laser which can selectively cause the laser to pulse, resulting in high energy pulses;
and a second lens for focusing an output pulse such that it creates a plasma or spark.
