The IAM-AWP is equipped with a variety of state-of-the-art laser sources for various laser material processing applications. UV laser sources are applied as well as fiber lasers, solid state lasers, CO2 lasers and ultrashort pulse lasers. For analysis of the processing results a wide range of characterization techniques are used. In addition to standard metallographic methods and materials characterization procedures, scanning electron microscopy, surface profilometry, X-ray diffraction, electrochemical analysis and contact angle measurement are available.
