SpaceX will sell satellite lasers to competitors that can accelerate space communication

With the continuous growth of user numbers and usage duration, the quality and reliability of the ALPD laser projection solution independently developed by the global laser display leader Guangfeng Technology (688007. SH) have been increasingly recognized by more and more users.It is reported that VOX Cinemas, a well-known cinema line in the Middle East, has also joined the ALPD laser projection s...

The attosecond level ultra short laser pulse provides a powerful method for detecting and imaging ultra short processes, such as the motion of electrons in atoms and molecules.Although ultra short laser pulses can be generated, generating ultra short and high-energy pulses is a continuous challenge. In order to expand the photon energy, photon flux, and continuous bandwidth of isolated attosecond ...

Recently, the research team of the High Power Laser Element Technology and Engineering Department of the Shanghai Institute of Optics and Mechanics, Chinese Academy of Sciences, has made new progress in the study of improving the damage threshold of fused quartz elements through laser cleaning. The study proposes for the first time the use of microsecond pulse CO2 laser cleaning to enhance the dam...

Due to the growing demand for renewable energy, the need for modern technologies to dismantle existing underwater infrastructure is also growing.For example, in order to boost the power of an offshore wind farm to a higher level, the existing old steel frame, which may be below sea level, must first be removed so that engineers can rebuild the steel frame for higher power.In laboratory tests, rese...

Recently, the team led by Professor Li Zhiyuan from South China University of Technology has successfully developed a full spectrum white light laser, which has the characteristics of bright spot, smooth and flat spectrum, and large pulse energy. It can cover the ultraviolet visible infrared full spectrum of 300-5000nm, with a single pulse energy of 0.54mJ.The launch of such a full spectrum white ...
