Influence of particle location within plasma and focal volume on precision of single-particle laser-induced breakdown spectroscopy measurements
TLDR
In this article, the effect of the location of particles within the plasma volume on the laser-induced breakdown spectroscopy signal for single-particle measurements is investigated, and three methods of collecting plasma emission are compared to determine the influence of plasma imaging on particle hit detection rates and signal precision.About:

Laser-Induced Breakdown Spectroscopy (LIBS), Part I: Review of Basic Diagnostics and Plasma–Particle Interactions: Still-Challenging Issues Within the Analytical Plasma Community
David W. Hahn,Nicoló Omenetto +1 more
TL;DR: Basic diagnostics aspects of laser-induced breakdown spectroscopy are focused on and a review of the past and recent LIBS literature pertinent to this topic is presented and previous research on non-laser-based plasma literature, and the resulting knowledge, is emphasized.

Laser Spectroscopy for Atmospheric and Environmental Sensing
Marc N. Fiddler,Israel Begashaw,Matthew A. Mickens,Michael S. Collingwood,Zerihun Assefa,Solomon Bililign +5 more
TL;DR: This review is focused on three areas of laser spectroscopic applications in atmospheric and environmental sensing; namely laser-induced fluorescence (LIF), cavity ring-down spectroscopy (CRDS), and photoluminescence (PL) techniques used in the detection of solids, liquids, aerosols, trace gases, and volatile organic compounds (VOCs).
Energy absorption and propagation in laser-created sparks - eScholarship
TL;DR: A spiky behavior is observed in the transmitted temporal profiles of lasers at higher energies and this is explained as due to the formation of a self-regulating regime.

Detection of bacteria by time-resolved laser-induced breakdown spectroscopy
TL;DR: Time-resolved laser-induced breakdown spectroscopy (TRELIBS) exhibits a good ability to differentiate among all these species, whatever the culture medium, the species or the strain, and is expected to be a good candidate for a sensor of hazards either on surfaces or in ambient air.

Laser-induced breakdown spectroscopy detection and classification of biological aerosols.
TL;DR: In this paper, a spectrally broadband laser-induced breakdown spectroscopy (LIBS) system was used for laboratory measurements on some common biological agent simulants, which were compared to those of common, naturally occurring biological aerosol components (pollen and fungal spores) to determine the potential of LIBS for discriminating biological agents from natural background aerosols.

Laser induced breakdown spectroscopy for the detection and classification of biological aerosols
TL;DR: A principal components analysis illustrates that linear combinations of the detected atomic lines, which are present in different ratios in each of the samples tested, can be used to discriminate biological agent simulants from other biological matter.
