The brittle failure of solids under the effect of pulsed electron beam is (PEB) of high-density was detected for the first time in semiconductor materials and subsequently also in ion crystals, glass and rock. The aim of this work was to examine the morphology of fracture of crystal dielectrics during the variation of the parameters of the pulsed e...

Ion implantation (II) is one of the most promising methods of surface treatment in resources-saving technologies, in particular, in the case of expensive rare metals. The aim of this work was the investigations of the special features of ion implantation of heavy metals, in particular, tungsten, in the frequency-pulsed regime using the modified sys...

Within the framework of the cooperation project, different media had been investigated which are suitable for 4WM (four-wave mixing) using pulsed CO_2 lasers. Furthermore, the resulting 4WM efficiencies were compared under identical conditions. PC (phase conjugate) reflectivities of 103% (SF_6), 44% (InAs), 20 (InSb) and 6-13% (organic solvents) co...
New experimental laser techniques have been applied for basic research on molecular clusters (benzene-argon, benzene-benzene, benzene-copper, silver-silver, niobium-niobium) in the gas phase. Informations on cluster sizes, state of energy, interactions and kinetics at defined cluster size were obtained using mass-selective hole-burning spectroscopy...

Part two of this final report describes the development of a contactless measuring system for steel section contour scanning. Different optical methods were compared. On account of its advantages over other methods the split-beam method was found to be the most suitable solution. The components required for system implementation are introduced and ...
