Abstract: The paper considers the conditions for the development of electrocapillary instability on the surface of micron and submicron metal droplets in laser torch plasma. Using a numerical model of the Langmuir layer, it is shown that the condition for the development of electrocapillary instability on the droplet surface in plasma differs significantly from the Rayleigh criterion. A dispersion relation was obtained for waves on the surface of the melt under the influence of plasma.

Keywords: laser electrodispersion, electrocapillary instability, laser plasma, cascade division.
