With the increasing number of drone players, incidents of "black flying" interfering with civil aviation have been repeatedly banned, and traditional air defense methods are difficult to attack such "low, slow and small" aircraft. "Low-altitude Guard ...

Although laser welding technology has been quickly accepted by the industrial field, the intelligent sensor technology that can realize online decision-making is still behind. Over the years, a variety of monitoring technologies that can be applied t ...

Fiber laser has become the tool of choice for many advanced and industrial batch welding applications. It can serve many mature industries and adapt to rapidly growing emerging markets. In the booming electric vehicle industry, the high-speed, precis ...

In a study recently published in the Journal of Synchrotron Radiation, Osaka University, the Japan Institute of Physics and Chemistry, and the Japan Synchrotron Radiation Institute worked together to reduce the beam diameter of the X-ray free electro ...

With a little red riding hood on his head, a big red box on his back, a portable tripod, a chubby figure with the free and easy atmosphere of a northern man, he has been running along the coastline of China Communications Construction Zhenhua Heavy I ...

Atoms are atoms with highly excited electrons. Researchers use laser pointer beams and rubidium atom clouds to create atoms. Rubidium atoms only need to absorb the energy of one photon to excite the outermost electrons to a higher energy level and be ...

Mobile phones are no longer a rare thing. Now they have become indispensable personal items in people's daily lives. Instant messaging, taking pictures, using APP, playing games and even paying for purchases, etc., are all inseparable from smart phon ...

Today, laser processing technology has become the darling of industrial applications due to its high efficiency, high precision, non-contact processing and other characteristics, opening up broad prospects for high-quality, efficient and environmenta ...

All interference gravitational wave detectors, such as LIGO, VIRGO and GEO600, rely on the laser pointer system and need to keep their high output power stable within a year, and their power fluctuations on the time scale are very small. The research ...

A year ago, people directly detected gravitational waves for the first time. laser pointer experts from the Planck Institute for Gravity Physics (Albert Einstein Institute AEI), and from the University of Leibniz Hannover, and from Hannover Laser Cen ...
