Research areas and established processes

  • Laserstructuring and annealing of electrode thin and thick films to improve performance (lifetime, high current capability) of lithium ion batteries (LIB) 
  • Development of materials processing with ultrashort pulse laser technology for micro- and nanostructuring of multimaterial systems and materials which are difficult to process under the aspect of biological applications.
  • Development ofprocesses for surface functionalization (e.g. wetting behavior), micro- and nanostructuring of surfaces and thin films for biological and microfluidic applications (e.g. in combination with microprinting technologies) 
  • Microstructuring of polymers with CO2-laser radiation  (Rapid Manufacturing)
  • Manufacturing of polymeric microsystems by laser transmission welding
  • Laser-LIGA and laser micro-caving for the generation of metallic microstructures (e.g. mold inserts) 
  • Laser microwelding of metals (e.g. production of microstructure machines)
