Abstract:
The challenges faced by the current inhabitants of Earth in relation to EEE (Energy, Economy, Ecology) issues on a macroscopic level, lead to numerous demands tied to decades-long timeframes, which not only affect humans but also flora and fauna. Research works from past centuries, once considered insignificant, have suddenly gained new validation and relevance. Many predictions, based on both material and immaterial facts, are either being confirmed or requiring new assessments. Considering several qualities of operations that have become part of the technological solution methods, regardless of the title of “laser damage, as a parallel to some other Elion technique, several types of commercial type materials were chosen, on which several of the same operations were carried out, primarily through laser techniques, but also mechanical and other techniques. This also applies to the term modulation of surfaces, or volume, local (with the somewhat flexible concept of "local", including issues of forming the beam cross-section of quantum generators, from ~nm to practical over ~cm (or larger) dimensions. For detector materials based on plastics, crystals with various dopants, or other components of the system, several exposures were performed, and a detailed analysis was conducted regarding microscopic changes (both electron microscope and light) in the final sample, depending on the chosen geometries and dimensions. Simulations of the processes, in term of expected dimensions of laser impacts (damage areas), LAZ, and HAZ, were analyzed and compared with our experiments (experimental parameters) or other parameters from existing literature.
