Recently, the research team of Yang Shanglu from the Laser Intelligent Manufacturing Technology R&D Center of the Chinese Academy of Sciences Shanghai Institute of Optics and Fine Mechanics has made new progress in the laser assisted connection of metal carbon fiber composite heterostructure joints.The team used an adjustable flat top rectangular semiconductor laser as a heat source to achieve...
Gallium nitride (GaN) vertical cavity surface emitting laser (VCSEL) is a semiconductor laser diode with broad application prospects in various fields such as adaptive headlights, retinal scanning displays, nursing point testing systems, and high-speed visible light communication systems. Their high efficiency and low manufacturing costs make them particularly attractive in these applications.Gall...
High energy, high average power femtosecond laser due to the attosecond high order harmonic generation, precision processing and manufacturing, biomedical and national defense and other fields of extensive application needs, is the forefront of ultrafast super laser technology research in the past decade.Especially fiber laser due to stable and reliable operation characteristics, compact structure...
Archaeologists have long wondered why the people of Anglo Saxon England began using more silver coins and fewer gold coins between 660 and 750 AD. Researchers in Europe now say they have developed a method to help find the answer. This technology combines laser ablation with traditional trace element analysis to match the isotopic abundance of silver bars in coins with known sources of metal ores ...
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...
