We considered possibilities of an application diffractive free-form optics in laser processing metallic materials aerospace production. Based on the solution inverse problem heat conduction, algorithm was developed that calculates spatial distribution power density irradiation order to create required thermal effect materials. It found use for beam shaping made it possible obtain specified prop...

The role of the plasma in laser–metal interaction is of considerable interest due to its influence in the energy transfer mechanism in industrial laser materials processing. A 10 kW CO2 laser was used to study its interaction with aluminium under an argon environment. The objective was to determine the absorption and refraction of the laser beam through the plasma during the processing of alumi...

Today the laser technologies are widely used in the processing of materials, including also the precise microshaping. Deep UV lasers have very good prospects in the lithography, used for fabrication of chips, while the femtosecond pulsed lasers open the new horizons for the microand submicroprofilling. But these are the field of the future prospects. As for today state-of-the-art, contribution ...

Recent advances in laser peening technology, also known as laser shock processing (LSP) are reported. Specific emphasis is placed on its development in the micro scale regime. LSP imparts desirable residual stress distributions into the target material in order to improve the fatigue life of the material. In modeling improvements, plasma expansion is modeled as laser supported combustion wave, ...

Certain microstructural features of materials, such as grain size in metals, porosity in ceramics, and structural phase compositions, are important for determining mechanical properties. Many of these microstructural features have been characterized by ultrasonic wave propagation measurements, such as wave velocity and attenuation. Real-time monitoring of ultrasonic wave propagation during the ...

Next generation magnetic microwave devices will be planar, smaller, weigh less, and perform well beyond the present state-of-the-art. For this to become a reality advances in ferrite materials must first be realized. These advances include self-bias magnetization, tunability of the magnetic anisotropy, low microwave loss, and volumetric and weight reduction. To achieve these goals one must turn...
