The article presents the results of high-speed spectral measurements of the emission spectrum of plasma-vortex formations formed by an atmospheric pulsed plasma torch based on an electrical explosion of a conductor. Spectrum registration is carried out in the stage of autonomous existence of vortex formations. It is shown that the emission spectrum contains the Planck continuum, due to the presence of condensed oxides, and the molecular bands of AlO. Based on the obtained data, the dependence of the temperature dynamics over time was obtainedby the method of spectral pyrometry.

A new approach to the treatment of wound lesions, which are complicated by the presence of polyresistant microflora and a possible immunodeficiency background has been proposed. It involves treating the wound surface with high-intensity pulsed optical radiation of a continuous spectrum, continuously covering the entire UV range (from 200 to 400 nm), visible and near infrared region of the spectrum. A pulsed xenon lamp is used as a radiation source. A description of the design and technical characteristics of the developed device for high-intensity optical irradiation "Zarnitsa-A", which implements the proposed medical technology for wound therapy, is represented. The results of preclinical studies of the apparatus in vitro and in vivo are represented hereinafter. The article shows that the apparatus exposure has pronounced bactericidal and wound-healing properties. The apparatus action reliably provides higher rates of wound healing compared to the use of only a typical antibacterial and wound healing agent – “Levomekol” ointment.

The paper presents the results of a study of the developed pulsed plasma generator based on the cylindrical foil electric explosion. The generator is used to form large-scale toroidal plasma vortices in atmospheric air. The influence of the specific stored energy on the phase composition of the plasma flow and the lifetime of plasmoids using a high-speed camera was studied. It was found that large condensed particles in the flow do not participate in the vortex motion and cause the destruction of plasma vortices. The formation conditions of stable plasma vortices were determined.
