High power solid-state laser

Research on the physical basics for a multi kw. Solid-state
laser with high energy and good beam quality; study process
principles, design prototype and scale results to maximum
average power for processing.

Objectives: - to research on the physical basics for a multi-kilowatt solid-state laser with high energy and good beam quality. - to study process principles and requirements for all components in the high mean power region. - to design and create a prototype of a high power solid-state laser with sufficient beam quality and high efficiency. - to design and test all necessary components for beam handling; optics, fibre, etc. - to scale the results to the maximal average power for processing. Background: The pulsed solid-state laser, because of its wavelength and its peak power, is already capable of welding all metallic materials - insofar as this is metallurgically possible - and cutting all such metallic and various non-metallic materials. Today, the applications are limited to small parts required in electrical and precision engineering. With higher average power, and especially with higher pulse energy, economic processing can also be achieved on large component sizes equivalent to the current application range of the CO2 laser. The latter point implies that two laser processes, a supplement to each other's capabilities, will be available. In view of their different wavelengths, they will be aimed at different sets of applications both as far as the materials that are to be processed are concerned, and the beam transmission facilities.
