Shijia Photon disclosed its 2024 annual performance forecast on the evening of January 17th, expecting to achieve a revenue of 1.074 billion yuan in 2024, a year-on-year increase of 42.36%; Net profit attributable to the parent company was 65 million yuan, with a loss of 47.55 million yuan in the same period last year; Deducting non net profit is expected to be 48.1 million yuan, with a loss of 66...
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. ...
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...
They are the strongest lasers in history, and their beams are helping scientists explore the structure of the universe.In a research laboratory at the University of Michigan, bright green light fills the vacuum chamber of a technology giant. It is the size of two tennis courts. The walls are shielded with 60 centimeters of concrete to prevent radiation leakage, and workers wear masks and hairnets ...
A new laser generation method: a laser without a reflector. This study, conducted by a team of physicists from the University of Innsbruck and Harvard University, shows that quantum emitters with spacing smaller than the wavelength can achieve constructive synchronization of photon emission, resulting in bright and extremely narrow bandwidth beams, even without any optical resonant cavities.The ac...
