In recent years, the secondary battery equipment sector in South Korea has been hit by a wave of disruption, with demand temporarily stagnant and stock prices struggling to gain support. Especially for Youil Energy Tech, a manufacturer of secondary battery equipment, as the company is a latecomer to the laser equipment market, its sales cost burden is relatively high. It is expected that in the future, the performance of Youil Energy Tech enterin...

The laser additive manufacturing technology of pure copper (Cu) with complex geometric shapes has opened up vast opportunities for the development of microelectronic and telecommunications functional devices. However, laser forming of high-density pure copper remains a challenge.Recently, the forefront of additive manufacturing technology has noticed a joint report by the University of Hong Kong, The Chinese University of Hong Kong, and the Unive...

IntroductionThe small hole mode swing laser welding has gained increasing recognition due to its ability to bridge gaps, refine microstructures, and enhance the mechanical properties of welds. However, the effects of amplitude, frequency, welding speed, laser beam power, and beam radius on heat flux distribution, melting mode, and three-dimensional temperature field have not been well understood. To meet this demand, we report a combined experime...

Recently, the Thin Film Optics Research and Development Center of the High Power Laser Component Technology and Engineering Department of the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, collaborated with researchers from Hunan University and Shanghai University of Technology to make new progress in the study of laser damage performance of mid infrared anti reflective coatings. The research team has developed a 6-...

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 of grating height and upper base angle need to be...
