Résumé:Title screen
An experimental setup and a technique for measuring the temperature and concentration of carbon and barium oxide particles in an ionized dispersed medium are described. It is shown that in a wide-aperture Nd laser beam at a wavelength of 1.06 µm with a pulse duration of ~1 ms, the ionization threshold of a carbon dispersed medium is lower than the ionization threshold of a focused beam. The ionization threshold is 5-10 times higher for the medium with barium oxide particles (with a low ionization potential) than for the medium with carbon particles for both focused and wide-aperture beams. It has been experimentally confirmed that exothermic reactions prevail over other processes during ionization of the examined media.
