国内自主研发首套碳化硅晶锭激光剥离设备投产

With the prominent energy issues in various countries around the world, the utilization and development of energy have become a hot topic, and the demand for renewable energy is constantly increasing. The existing underwater infrastructure is no longer sufficient and needs to be dismantled using appropriate modern technology. For example, in order to increase the power of offshore wind power plant...

Recently, a team from the National Key Laboratory of Ultra strong Laser Science and Technology at the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, collaborated with the Arctic University of Norway (UiT) to make progress in the efficient cracking of high-density polyethylene (HDPE) using strong laser molecular bond breaking technology. The research results were publ...

From detecting COVID in respiration to monitoring greenhouse gas concentrations, laser technology called frequency combs can recognize specific molecules as simple as carbon dioxide to as complex as monoclonal antibodies, with unparalleled accuracy and sensitivity. Although frequency combs have incredible capabilities, their ability to capture high-speed processes such as hypersonic propulsion or ...

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...

Most traditional quantum computing uses the spin of supercooled atoms or individual electrons as quantum bits, which form the foundation of such devices. By comparison, if light is used to replace physical entities as basic quantum bits, ordinary lenses and optical detectors can replace expensive devices to control the data input and output of quantum bits.Based on this, chemistry professors Moung...
