TL;DR: The first laser-induced breakdown spectrometer (LIBS) was used on the Mars Science Laboratory (MSL) rover Curiosity for remote compositional information using the first LIBS on a planetary mission, and provided sample texture and morphology data using a remote micro-imager.
Abstract: The ChemCam instrument suite on the Mars Science Laboratory (MSL) rover Curiosity provides remote compositional information using the first laser-induced breakdown spectrometer (LIBS) on a planetary mission, and provides sample texture and morphology data using a remote micro-imager (RMI). Overall, ChemCam supports MSL with five capabilities: remote classification of rock and soil characteristics; quantitative elemental compositions including light elements like hydrogen and some elements to which LIBS is uniquely sensitive (e.g., Li, Be, Rb, Sr, Ba); remote removal of surface dust and depth profiling through surface coatings; context imaging; and passive spectroscopy over the 240–905 nm range. ChemCam is built in two sections: The mast unit, consisting of a laser, telescope, RMI, and associated electronics, resides on the rover’s mast, and is described in a companion paper. ChemCam’s body unit, which is mounted in the body of the rover, comprises an optical demultiplexer, three spectrometers, detectors, their coolers, and associated electronics and data handling logic. Additional instrument components include a 6 m optical fiber which transfers the LIBS light from the telescope to the body unit, and a set of onboard calibration targets. ChemCam was integrated and tested at Los Alamos National Laboratory where it also underwent LIBS calibration with 69 geological standards prior to integration with the rover. Post-integration testing used coordinated mast and instrument commands, including LIBS line scans on rock targets during system-level thermal-vacuum tests. In this paper we describe the body unit, optical fiber, and calibration targets, and the assembly, testing, and verification of the instrument prior to launch.

TL;DR: In this article, a review of recent results of the studies of double laser pulse plasma and ablation for laser induced breakdown spectroscopy applications is presented, where the authors demonstrate that the maximum effect is obtained at some optimum separation delay time between pulses, which depends on several factors, such as the target material, the energy level of excited states responsible for the emission, and the type of enhancement process considered.

TL;DR: A review of the current experimental approaches used for obtaining quantitative micro-analysis using the laser-induced breakdown spectroscopy (LIBS) technique can be found in this paper, where the influence on LIBS analytical performances of laser power, wavelength and pulse length, the proper choice of experimental geometry, the importance of ambient gas choice and the role of detectors for improving the precision of LIBS analysis are discussed.

TL;DR: In this paper, a laser-induced breakdown spectroscopy was applied to perform elemental analysis of aluminum alloy targets, and a plasma was generated by focusing a pulsed Nd:YAG laser on the target in air at atmospheric pressure.
Abstract: Laser-induced breakdown spectroscopy has been applied to perform elemental analysis of aluminum alloy targets. The plasma is generated by focusing a pulsed Nd:YAG laser on the target in air at atmospheric pressure. Such a plasma was characterized in terms of its appearance, emission spectrum, space-integrated excitation temperature, and electron density. The electron density is inferred from the Stark broadening of the profiles of ionized aluminum lines. The temperature is obtained by using Boltzmann plots of the neutral iron lines. Calibration curves for magnesium, manganese, copper, and silicon were produced. The detection limits are element-dependent but are on the order of 10 ppm.
