Recently, according to the information of the China National Intellectual Property Administration, Zhejiang Sunny Optics Co., Ltd. has obtained a patent named "Optical Imaging Lens", with authorization announcement No. CN221899396U and application date of 2024-01-31.The patent abstract shows that the present application discloses an optical imaging lens, comprising a barrel and first to eighth len...
Modern laser technology urgently requires nonlinear optical materials that can generate coherent light through second harmonic generation. However, only a small portion of the nonlinear optical properties of non centrosymmetric crystal materials have been experimentally or theoretically studied, and exploration for high-performance nonlinear optical crystal materials is still very limited.Recentl...
Recently, scientists from the Hanover Laser Center (LZH) in Germany announced the successful development of an automated laser drilling process that can promote the processing of carbon fiber reinforced plastics (CFRP). They stated that this is particularly valuable in applications such as lightweight structures and sound insulation.Composite materials such as carbon fiber reinforced plastics (CFR...
According to the Physicists' Network, scientists from Lawrence Livermore National Laboratory (LLNL) in the United States ingeniously combined the high-power laser emitted by the National Ignition Facility (NIF) with the ultra light metal foam to create the brightest X-ray ever. These ultra bright high-energy X-rays play an important role in many research fields, including imaging of extremely dens...
Photoacoustic tomography (PAT) is a novel hybrid medical imaging technique that enables precise imaging of biological tissue structures at different spatial scales. It has been widely used in various fields, including brain imaging, cancer detection, and cardiovascular disease diagnosis. However, due to limitations in data acquisition conditions, photoacoustic tomography systems typically can only...
