The green and blue laser diode series provides higher beam quality

The optical properties of afterglow luminescent particles in mechanical luminescence and mechanical quenching have attracted much attention in various technological applications. A group of researchers from Pohang University of Science and Technology has attracted attention by developing an optical display technology with ALP that can write and erase messages underwater.The team is composed of Pro...

Laser soldering is widely used in the manufacturing of automotive parts. Here are some common automotive parts that can be welded using laser soldering:Automotive electronic control systemEngine Control Unit (ECU): The engine control unit is the "brain" of the car engine, which receives signals from various sensors and controls the operation of the engine based on these signals. Laser soldering ca...

Recently, a research team led by Professor Cai Wei and Professor Xu Jingjun from the School of Physical Sciences at Nankai University has experimentally confirmed for the first time the generation of polaritons, also known as Smith Purcell radiation, at the two-dimensional scale, and further demonstrated the ability of free electrons to regulate two-dimensional Smith Purcell radiation. The researc...

The SCALA 3 LiDAR (Laser Detection and Ranging System), the third generation LiDAR scanner from Valeo, won the "Vehicle Technology and Advanced Mobile Mobility" Innovation Award at the 2024 CES Consumer Electronics Exhibition.The first and second generation Fareo LiDARs SCALA 1 and SCALA 2 have achieved autonomous driving in traffic congestion situations. The third-generation LiDAR SCALA 3 has sig...

For example, the commonly used square shell battery cells for power batteries include laser welding of cover explosion-proof valves, laser welding of pole columns, and laser welding of cover plates and shells. During the process of laser welding of aluminum alloy, it is easy to generate unqualified phenomena such as explosion points, pores, welding cracks, excessive depth and width of fusion. ...
