There is a growing industrial need for compact, highly efficient and maintenance free laser sources with high power and a long lifetime. With diode pumped solid state lasers such sources are feasible. The reseach of the scientifical and technical basics for this lasers was the target of this project. The main target of the part project done by ADLAS was to work out the basics for a frequency doubled TEMoo laser with more thant 10 W and an efficiency of better 0.5 percent. The reseach on the needed pumping modules for side- and endpumping lasers is reported intensively. 'Experiments with the different pumpmodules in side- and endpumped lasers with and without frequency doubling were studied intensively. It was shown that endpumped lasers are very much more efficient and scalable with fiber coupled laser diodes. We demonstrated a frequency doubled power of 10.7 W with an overall efficiency of better 2 percent.
