Ultraviolet spectroscopy plays a crucial role in the study of electronic transitions in atoms and rovibronic transitions in molecules. These studies are crucial for the testing of fundamental physics, quantum electrodynamics theory, determination of fundamental constants, precision measurements, optical clocks, high-resolution spectroscopy supporting atmospheric chemistry and astrophysics, and str...
Scientists at Purdue University in the United States have developed a new type of two-photon polymerization technology. This technology cleverly combines two lasers and utilizes 3D printing technology to print complex high-resolution 3D structures while reducing femtosecond laser power by 50%. It helps to reduce the cost of high-resolution 3D printing technology, thereby further expanding its appl...
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 Technical University of Munich in Germany have reported a feasibility study on the composite manufacturing of EN AC-42000 alloy by combining laser powder bed melting and cold casting. The related research titled "Feasibility study on hybrid manufacturing combining laser based powder bed fusion and chill casting on the example of EN AC-42000 alloy" was publi...
