“…Atomic and molecular clusters have been subject to continuous interest over many years 59 , 60 and much interest has been devoted to their possible ground state geometrical structures and properties. Many ICD experiments have been carried out with rare gas clusters 21 and as the interaction of the atoms is weak this makes them particularly suitable for cavity investigations.…”

The interatomic Coulombic decay (ICD) is an efficient electronic decay process of systems embedded in environment. In ICD, the excess energy of an excited atom A is efficiently utilized to ionize a neighboring atom B. In quantum light, an ensemble of atoms A form polaritonic states which can undergo ICD with B. Here we investigate the impact of quantum light on ICD and show that this process is strongly altered compared to classical ICD. The ICD rate depends sensitively on the atomic distribution and orientation of the ensemble. It is stressed that in contrast to superposition states formed by a laser, forming polaritons by a cavity enables to control the emergence and suppression, as well as the efficiency of ICD.

“…An experimental setup, used to obtain LIBS spectra from various materials, generally consists of a high-intensity pulsed laser system, with nanosecond laser pulse duration, an experimental chamber, a collection optics, and a high-precision optical spectrometer. Plasma is generated by focusing the high-intensity laser pulses into the material; usually a Nd:YAG laser is applied at its fundamental laser wavelength of 1064 nm or its second harmonic 532 nm with different repetition rates from 1 Hz to a few kHz [25][26][27]. A schematic of the experimental LIBS setup is shown in Figure 2.…”

In this research we apply a sensitive laser optical technique for the measurement of main chemical elements present in the exhaust emissions generated from different in-use Diesel engine passenger vehicles. We use the laser-induced breakdown spectroscopy (LIBS) technique for diagnostics of miscellaneous Diesel particulate matter (DPM) formed from combustion Diesel engine exhaust emissions. Here we analysed particulate matter (PM) extracted from exhaust manifold part, from 67 different passenger vehicles of major brands from European car producers, that are used in daily life environment. The aim of this study is to develop LIBS technique for measurement of PM and to compare the emission matrix composition and major chemical elements within the Diesel particulate matter from exhaust manifold part. The presence of these elements in PM is linked with various processes inside the Diesel combustion engine.

“…The delay time for starting recording of the optical spectral signal was set to 1 µs after the trigger signal, and gate time for spectral acquisition has been set to 2 µs. In earlier delay times than 1µs, the black body radiation dominates in the laser-induced plasma, while for later time intervals like 3 µs the atomic and ionic emissions start decaying [46]. The LIBS emission was measured in an open air atmosphere under atmospheric pressure and at room temperature.…”

In this research we apply a high-resolution optical emission spectroscopy technique for spectrochemical analysis of collected diesel particulate matter. We use the laser-induced breakdown spectroscopy technique (LIBS) for qualitative and quantitative measurements of major chemical elements present in the particulate matter generated from different diesel engine passenger vehicles in use. The high-resolution LIBS technique can instantly measure major chemical elements within the diverse particulate matter matrices.
