Abstract: A LIBS analyzer and method includes a laser configured to produce a plasma on a sample at a focal point on the sample and a spectrometer responsive to radiation emitted from the plasma and configured to produce an output spectrum. A detector is positioned to detect low intensity pre-firing radiation produced by the laser and reflected off the sample from the focal point. The intensity of the low intensity pre-firing radiation is compared to a predetermined minimum and the laser pump sequence is halted if the intensity of the low intensity pre-firing radiation is less than the predetermined minimum.

Abstract: A LIBS analysis method and apparatus wherein multiple laser firings in a burst mode are produced to clean a location on the sample. Subsequently. for data collection, pumping the laser produces one or more analysis laser firings and when such a laser firing is detected, the laser pumping stops and the method includes initiating a delay period of time after which the spectrometer is triggered to begin analysis of the resulting plasma produced on the sample.

Abstract: A handheld LIBS analyzer includes a laser source for generating a laser beam and a spectrometer subsystem for analyzing a plasma generated when the laser beam strikes a sample. A nose section includes an end plate with an aperture for the laser beam, a purge cavity behind the aperture fluidly connected to a source of purge gas, and a shield covering the purge cavity. A vent removes purge gas from the purge cavity when the end plate is placed on the sample.

Abstract: An analysis (e.g., LIBS) system includes a source of radiation, an optical emission path for the radiation from the source of radiation to a sample, and an optical detection path for photons emitted by the sample. A detector fiber bundle transmits photons to the spectrometer subsystem. At least one fiber of the fiber bundle is connected to an illumination source (e.g., an LED) for directing light via at least a portion of the detection path in a reverse direction to the sample for aligning, sample presence detection, localizing, and/or focusing based on analysis of the resulting illumination spot on the sample.

Abstract: A handheld LIBS spectrometer includes an optics stage movably mounted to a housing and including a laser focusing lens and a detection lens. One or more motors advance and retract the optics stage, move the optics stage left and right, and/or move the optics stage up and down. A laser source in the housing is oriented to direct a laser beam to the laser focusing lens. A spectrometer subsystem in the housing is configured to receive electromagnetic radiation from the detection lens and to provide an output. A controller subsystem is responsive to the output of the spectrometer subsystem and is configured to control the laser source and motors. In this way, auto-calibration, auto-clean, and auto-focus, and/or moving spot functionality is possible.

Abstract: A handheld LIBS device and method includes a laser assembly producing two pulsed single spatial mode output beams and a focusing optic which combines the two pulsed single spatial mode output beams at a focal point at a sample. The laser assembly includes a laser assembly housing with an output coupler window for the two pulsed single spatial mode output beams, a gain medium in the laser assembly housing between the output coupler window and an adjustable prism mount in the laser assembly housing holding a prism configured to establish two light paths through the gain medium, a source in the laser assembly housing providing pump energy to the gain medium, and a Q-switch positioned between the prism and the gain medium.
