    On the Nature of Defects in Solid Structure under the Action of Laser Radiation with the Energy Not Destructing a Sample as a Whole

    Nature of the defects in solid samples generated under the surface irradiation by a pulse of a CO2-laser is investigated by the method of acousti©emission analysis. The laser pulse energy of 1.5 J was insufficien...

    Irreproducibility of acoustic emission under cyclic irradiation of solids by an infrared laser pulse

    Acoustic emission (AE) caused by a stress wave in solid material samples with various thermophysical properties, i.e., copper, aluminum, and glass upon exposure to СO2 laser pulses is studied. It is found that th...

    Investigation of the Infrared Absorption Spectrum of Neutron-Irradiated Silicon

    A departure from the periodicity of the crystal lattice (i.e., the presence of defects) in silicon, can, as in other semiconducting crystals, result in considerable changes in its electrical and optical proper...
