Recently, Alexander Wittmann published on the “Consolidation of thermoplastic coatings by means of a thulium-doped fiber laser”. He investigated the suitability of this laser for depositing polymer coatings on stainless steel substrates.

To optimize the layer morphology, he varied the main process parameters as laser power, scanning speed, and substrate temperature.

Alexander Wittmann works at the Institute of Photonic Technologies, his supervisor is Michael Schmidt. The original publication can be found in the Journal of Laser Applications.
