Laser Chemical Processing
|
|
The "Laser Chemical Processing" Research Group, headed by Prof. Dr. Michael Stuke, focusses on the interaction of laser radiation with surfaces, often in contact to suitable chemical environments. A detailed understanding of the initiated processes leads to two spectacular specific applications using the energy coupled in, which can be continuous wave cw or via short pulses: (a) Precise and efficient removal of materials by laser etching or/and laser ablation, in particular with vacuum-ultraviolet radiation at 157 nm (VUV) due to the consistantly achievable nanoscale precision, and (b) laser-direct-write of small 3-dimensional ceramic/metal structures by deposition from the gas phase using suitable volatile precursor molecules. In this way, small field cages can be created and successfully used for touch-free storage, "handling" and transfer of neutral micro- and nanoparticles in aqueous solution, including cells.
