“…2. The optical properties of gold are well known [48] and are explained by first-principles calculations [49]. The experimentally obtained σ( ω) and ε 1 ( ω) spectra for the Au-film nicely reproduce known literature results, namely a rapid break in the OC near 2.5 eV (which is related to the threshold of the interband absorption) and pure intraband absorption below ω < 2 eV.…”

Specifically, as shown, such an approach can be useful for studying the nature of unusual MO properties and the interfaces in MLF comprising the noble and 3d-transition metals (3d-TM). The high sensitivity of the applied spectroscopic methods for the monitoring of the solid-state reactions in the 3d-TM/Si MLF induced by ion-beam treatment or by thermal annealing is also demonstrated. The optical properties of various silicides formed spontaneously or induced by various treatments at interfaces are evaluated experimentally and compared with the results of first-principle calculations.

“…For aluminum joints, the reflected energy is approxi mately 80-90% of the nominal power of the source [27]. How ever, the optical absorption in aluminum and copper is increased substantially during the welding process due to the temperature increase at the focal point of the laser beam [41,42]. Also, in the particular case analyzed herein, the laser beam is locally trapped within the focal area between the Al-sheet and the Cu-tube (see Figs.…”

A finite element (FE) approach is developed to investigate the laser spot welding (LSW) of flat-plate solar absorbers and the stress and distortion fields that develop after fabrica tion and during operation. Numerical calculations at two different levels are carried out. At a microscopic scale, the details of a spot weld are analyzed. At a macroscopic level, a global approach is used to simulate the joining of the pipeline to the absorber plate and the "restoration" (flattening) process of the absorber. The simulated welding-induced distortion is compared with experimental measurements. The thermomechanical behavior o f a solar absorber under working conditions is also studied and operational stresses and the critical locations for structural failure are reported.
