On August 22nd, Mitsubishi Electric Corporation, a multinational electronics and electrical equipment manufacturing company, announced that it had successfully demonstrated laser optical frequency control using a new light source module, which is a key component of a high-capacity laser optical communication network to be deployed in outer space.It is reported that this module can generate 1.5 &mu...
From detecting COVID in respiration to monitoring greenhouse gas concentrations, laser technology called frequency combs can recognize specific molecules as simple as carbon dioxide to as complex as monoclonal antibodies, with unparalleled accuracy and sensitivity. Although frequency combs have incredible capabilities, their ability to capture high-speed processes such as hypersonic propulsion or ...
Researchers from Annamarai University in India and South Ural State University in Russia reported a comparative study of resistance spot welding and laser spot welding of ultra-high strength steel for automobiles. The related research was published in The International Journal of Lightweight Materials and Manufacturing under the title "A comparative study on resistance spot and laser beam spot wel...
In today's rapidly developing technological era, structured light laser technology has become an important tool in the fields of 3D measurement and image capture. The core of this technology lies in a magical device called Diffractive Optical Elements (DOE), which can precisely control and shape laser beams, creating various complex light patterns. But what exactly is DOE? How does it work? Let Ho...
Image source: Federal Institute of Technology in Lausanne, SwitzerlandScience and Technology Daily, Beijing, September 27th (Reporter Zhang Jiaxin) Commercial femtosecond lasers are manufactured by placing optical components and their mounting bases on a substrate, which requires strict alignment of optical components. So, is it possible to manufacture femtosecond lasers entirely from glas...
