Surface Modification by Rapid Solidification Laser and Electron Beam Processing,y, processing is carried out by rapidly traversing (scanning) a high power density beam over the material surface, so as to induce melting of a thin surface layer. A high rate of energy delivery facilitates surface melting at very high melting efficiency, such that most of the absorbed energy is use

,Structure — Property Relationships in Metallic and Oxide Glasses,a property is primarily dependent on the immediate coordination polyhedron centred on a given atom — the “l(fā)ocal structure” — then a semi-quantitative understanding is possible. This is the case for the optical properties of oxide glasses at energies above about 1eV. If, however, a physical property
