The group Surface Processing is divided into two subsections:
Section 1 deals with femtosecond laser surface processing of various materials ranging from metals and metal alloys to polymers or even composites. The extremely short interaction time of femtosecond laser pulses with matter offers extraordinary surface characteristics. The micro- and nanostructures arising on the substrates can be exploited for efficient cooling, enhanced absorption, or even to enlarge the catalytic effect of electrodes for water electrolysis.
The research and development of section 2 is focused on acoustics. Mainly based on fiber optic sensors, systems of sound detection in air or under water are developed. Customer-specific needs or application driven parameters strongly affect the sensor and system evolution within this section.
Customized photoacoustic gas detection systems are scope of the acoustics section, too. A unique, miniaturized detection technique enables fast and even fiber coupled sensing of various species.
