Recently, Qing Guangyan, a researcher team from the Research Group on Bioseparation and Interface Molecular Mechanism (1824 Group) of Biotechnology Research Department of Dalian Institute of Chemical Physics, Chinese Academy of Sciences, designed and prepared a highly solid cellulose photonic hydrogel with reconfigurability and mechanical discoloration. This preparation method opens up a new way t...
Researchers at the University of Rochester have created new micro comb lasers that go beyond previous limitations and have simple designs suitable for various applications. The research results are published in Nature Communications.Optical frequency combs are optical measurement instruments that have revolutionized atomic clocks, spectroscopy, metrology, and other fields. However, the difficulty ...
Laser material processing has been widely used in advanced industries, ranging from designing and producing lightweight, ultra wear-resistant parts and equipment with complex geometric shapes to repairing damaged or worn components through technologies such as 3D printing of deposited metal powders or deposits.Use laser pulses for surface treatment to prevent fatigue. But the impact of such techno...
Chinese industrial 3D printer manufacturer Huashu High tech has launched the FS811M metal powder bed fusion series platform. The FS811M series has a construction volume of 840 x 840 x 960 millimeters and can be equipped with powerful 6, 8, 10, or 12 x 500 watt fiber lasers."As the latest member of the Huashu High tech Metal 3D printer product portfolio, FS811M originates from our joint innovation ...
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...
