Abstract
Current trends in development of technological CO2-lasers, optically excited sold-state lasers and semiconductor lasers are analysed on the basis of the information obtained at Fair «Laser-2005» and Essen Fair «Schweissen and Schneiden». Technological parameters of fibre and semiconductor lasers have been improved in the last years, while those of CO2-lasers have remained almost unchanged. Two-coordinate scanning is additionally applied in technological systems based on the Cartesian manipulators. In welding technologies, the special consideration is given to combined welding methods, characterised by combined application of laser radiation and other heat sources, such as electric arc, non-coherent light sources, etc.
Keywords: technological lasers, CO2-lasers, disk and fibre solid-state lasers, technological laser systems, combined welding methods
