High-power impulse YAG laser system for cutting, welding and perforating of super hard materials

Wide application of high-productive materials such as tungsten, titanium, tantalum, niobium, aluminium, ceramics has determined the processing technology in the 21st century. These materials are used for aerospace, nuclear industry, shipbuilding, etc. Laser units make it possible to achieve the results, but their application is practicable with substantial increase of power, energy and generation of required pulse frequency emission. Cavity updating, optimisation of processing modes is finally connected with optimisation of welding, cutting, perforation parameters. In the long run, solution of this problem provides reliability and long life both for separate assemblies and for the whole products [S.V.
