Abstract

Over the last 17 years more than 60 lasers have been developed at Battelle-Frankfurt. Part of the corresponding work is described below. In particular we report on the development of various CO₂ TEA lasers and continuous high power CO₂ lasers. Preionisation is effected in the TEA lasers by UV light generated in a corona discharge. The TEA lasers of the last generation are particularly compact, reliable and efficient. They operate with pulse frequencies of up to 30 Hz and a mean power of up to 100 W. After the development of a continuous 1.2 kW high power CO2 laser of conventional design, the first gas transport laser was constructed in 1971. Knowledge and experience gained with this laser were the basis for various patent applications. The new developments in this area are based on these patents. At present two different gas transport lasers with 1 kW and 2 kW output power are being completed and tested. After selection of the most favourable principle a 5 kW system will be built. The new lasers differ from the known systems by the complete integration of the various components and the use of particularly efficient blowers. Their volume and weight will be lower by a factor of 3 or more.
