Paper Abstract

Resonator design as well as the control of the beam shape are essential for successful application. A huge flat bed system (3,5 x 2,5 m) called 'Big Bertha' and a long optical bench (12 m) called 'Long Bertha' with flexible beam rails has been build as a basic research setup. Allmost all kinds of laser sources, optical components and measurement devices can be mounted and easily positioned with a special system called 'Beam Rail'. Additionally a twin hexapod operated beam expander with variable lenses can be used e.g. in order to optimize magnification factors for AOMs. Results of accurate M2 measurements of different laser sources are presented as well as the influence of various optical elements and examples for close to perfect beam paths are given.
