Xinjiang Institute of Physical and Chemical Technology has established the largest database of computational nonlinear optical crystal materials to date

The gravitational wave background was first detected in 2016. This was announced after the release of the first dataset by the European pulsar timing array. The second set of data has just been released, combined with the timed array of Indian pulsars, and both studies have confirmed the existence of the background. The latest theory seems to suggest that we are seeing a comprehensive signal of th...

In the interaction between ultra short and ultra strong lasers and matter, short pulse width and high energy electrons are generated, commonly referred to as "hot electrons". The generation and transport of hot electrons is one of the important fundamental issues in high-energy density physics of lasers. Superhot electrons can excite ultrafast electromagnetic radiation in a wide range of wavelengt...

Tongkuai Optoelectronic Devices, a global leader in vertical cavity laser emitters (VCSEL) and laser diodes (PD) solutions based in Germany, and a Spanish expert in high-speed optical network solutions, KDPOF, showcased the first 980 nm multi gigabit interconnect system for automotive systems at last week's ECOC.Both companies are committed to achieving the most advanced optical data communication...

backgroundThe Jörg Debus team from the Technical University of Dortmund in Germany is dedicated to researching optical quantum information processing and quantum sensing in materials with potential applications. The team mainly studies the fine structure of materials under light fields, such as quantum dots, quantum effects of two-dimensional materials, semiconductor defects in diamonds, and ...

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...
