- Abstract
The character of the intensity distribution inside a cylindrical microparticle of chalcogenide glass is established to be nonuniform and determined by the cylinder radius. Depending on the microcylinder radius, regions of maximal intensities of the internal field are located in the illuminated or shadow parts of the cylinder (or in both the parts simultaneously) near the surface of the cylindrical particle and can exceed the incident radiation intensity by a factor of 2-4 as R < 2 μm. Heating occurs first in the shadow part of the microcylinders, then in both parts simultaneously, and then only in the illuminated part of the cylinders near their surface. This depends on the microcylinder radii and is caused by the manifestation of optical properties of the microcylinder substance and by the action of the heat transfer mechanism.
