Summary:To filter out infrared light from the driving light source in the extreme ultraviolet lithography (EUVL) light source system, a rectangular grating structure needs to be fabricated on the surface of the collection mirror. However, the collection mirror grating usually undergoes deformation during the manufacturing process, resulting in a decrease in filtering efficiency. The process errors...
It is reported that researchers from the University of Waterloo in Canada have reported a study on the plasticity of copper oxide nanowires induced by femtosecond laser. The related research was published in Applied Surface Science under the title "Femtosecond laser induced plasticity in CuO nanowires".Metal oxide nanowires are ideal materials for manufacturing nanodevices, especially strain senso...
A research team in France has reported a novel laser that emits light in the orange region of the spectrum, indicating its potential applications in flow cytometry and astronomical laser guidance.In the research results just published in Optics Express, the team (including researchers from the É cole Polytechnique in Caen, France and Oxxius, a laser manufacturer based in Lannion) claimed that the ...
The research from the University of West Virginia has been rewarded, as debris scattered in planetary orbits that pose a threat to spacecraft and satellites may be pushed away from potential collision paths by a coordinated space laser network.Hang Woon Lee, director of the Space Systems Operations Research Laboratory at the University of West Virginia, said that artificial debris dumps, including...
Recently, German laser giant Trumpf released data for the fiscal year 2023/24. The latest financial report shows that the group's sales decreased by 4% and order volume decreased by 10% in the fiscal year 2023/24.Despite these setbacks, Germany has become the company's strongest single market for the first time in many years, highlighting a shift in market dynamics.At the end of this fiscal year, ...
