<p>The efficiency of remote cutting and drilling of metal plates by laser radiation of high-than-average intensity has been determined. Spatial distributions of the electron temperature have been measured in the plasma jet of a laser plasmatron operating on a mixture of argon with molecular gases at atmospheric pressure; diamond coatings have been synthesized on the surface of a tool from hard alloy under jet-scanning conditions. Coatings of aluminum nitride and titanium have been obtained on a steel substrate with laser radiation of a dust-laden gas medium in the form of free vertical jet of microparticles in the gas. Parameters of nucleate boiling crisis have been determined on simulators of a fuel-element jacket in quiescent water at atmospheric pressure as functions of the rate of heating of the jacket by laser radiation.</p>
