Recently, the team led by Academician Guo Guangcan from the University of Science and Technology of China has made significant progress in the research of quantum elliptical polarization imaging. The research group of Professor Shi Baosen and Associate Professor Zhou Zhiyuan combined high-quality polarization entangled light sources with classical polarization imaging technology to observe the bir...
Researchers at the University of St. Andrews in Scotland have manufactured the first organic semiconductor laser to operate without the need for a separate light source - which has proven to be extremely challenging. The new all electric driven laser is more compact than previous devices and operates in the visible light region of the electromagnetic spectrum. Therefore, its developers stated that...
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. ...
Polyart has launched a new generation of Polyart laser printers, designed specifically for dry toner printing technology, with a completely improved coating formula and many exciting new advantages. These include reducing nationalism, moisture resistance, and better paper touch.Say hello to the good paper jogging on the printer output. More importantly, our new formula provides better scratch resi...
Topological laser (TL) is a laser device designed and manufactured using the principles of topological optics, which can produce a robust single-mode laser and is an ideal light source for future new optoelectronic integrated chips. Electrically pumped topology lasers have become a research hotspot due to their small size and ease of integration, but topology lasers based on electrical injection a...
