Abstract
A compact laser system based on a Nd: YAG laser with a wavefront self-reversal for remote analysis of substances by laser-induced breakdown spectroscopy at a distance of at least 10 m is proposed. The possibility of creating a reliable system for remote diagnostics of materials by laser-spark emission spectroscopy, including in real time, is shown.
Highlights
The measurements by use of the proposed Laser-induced breakdown spectroscopy (LIBS) system were carried out in two different laser operation regimes: passive Q-switching in the mode of generating a single pulse or a train of two pulses, as well as self-Q-switching on an outer plasma mirror

An LIBS system with high energy and spatial characteristics of laser radiation based on a small-size pulsed Nd:YAG laser with self-phase conjugation during the multiwave interaction in an active medium and passive Q-switching (PQS) is proposed for the first time
