Dr. Andreas Michalowski

Photonics – manufacturing with light

“If you are really drawn to a special topic, then you should also dive deeply into it even when a direct use for it is not immediately obvious. When you are intrinsically motivated in this way, that’s when you often learn the most. On many occasions I have experienced that at some point something new can emerge from the combination of this knowledge with other knowledge.”

Dr. Andreas Michalowski, Senior Expert for ultrashort pulse laser material processing

I am a passionate researcher in the field of laser production engineering, and as a senior expert at Corporate Research, I am responsible for the bases and simulation of laser processes with ultrashort-pulse lasers. We harness light for the manufacture of high-precision products possessing entirely new features.

Interview

Dr. Andreas Michalowski

Dr. Andreas Michalowski

Senior Expert for ultrashort pulse laser material processing

“Please tell us what fascinates you most about research.”

As a researcher, I have the opportunity to find out something that no other person before me has ever known. Typically, a researcher uses observations very creatively to develop generalized hypotheses or models, which are then verified in carefully designed experiments. If the predictions prove not to be true or to be only partially so, this is a great incentive to develop new ideas. When a model you have developed yourself makes correct predictions, this gives you an indescribable feeling. What’s more, you get to work with highly interesting people.

“What makes research done at Bosch so special?”

As a researcher at Bosch you have very good opportunities to design research topics using new ideas. So a large research project can grow out of your own idea. It is something very special for a researcher to be able to directly see how their own research results are implemented in practice. Besides, the general conditions for creative and successful research here are extremely good. Apart from top-tier, state-of-the-art laboratory equipment, this also includes ideal conditions at the wonderful research campus allowing excellent scientists from a variety of fields to do interdisciplinary work together. What unites us is the drive to develop new products that are “Invented for life” and thus make Bosch sustainably successful.

“What research topics are you currently working on at Bosch?”

We irradiate workpieces with beams of focused, ultrabright light pulses that are 100 billion times faster than the blink of an eye. The extremely fast and spatially very precise energy input that this provides makes it possible to structure, drill, or modify workpieces with micrometer precision and practically without causing unwanted damage. At the moment I am doing research to better understand the physical processes taking place in order to adapt the technology for new applications.

“What are the biggest scientific challenges in your field of research?”

The numerous physical effects of laser material processing are highly dynamic on very short time scales and small dimensional scales. This makes observing them with temporally or spatially resolved experiments very complex. At the same time, many of these effects can strongly influence each other in a real laser process. This makes it difficult to systematically examine the influence of individual factors on the overall process. In addition, the material parameters at the high temperatures and pressures that occur are usually not known precisely enough for a theoretical description.

“How do the results of your research become part of solutions "Invented for life"?”

The results of our research help in the manufacture of new products which possess improved or entirely new features while at the same time satisfying the highest standards of precision and reliability. This could be, for instance, products in the field of medical technology, but also new sensors or components for energy-efficient and low-emission or even emission-free mobility.
