The widespread application in the fields of optical communication, computing, and sensing continues to drive the growing demand for high-performance integrated photonic components. Recently, Ali Najjar Amiri of Kochi University in Türkiye and other scholars proposed a highly scalable and highly flexible deep photonic network platform, which is used to realize optical systems on chip with arbi...
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...
Liquid pulse laser ablation is a reliable and versatile technique for producing metal nanoparticles in solution. Its advantages include no reducing agent, simple operation, high purity, no need for purification steps, and environmental processing conditions, making it the preferred method for traditional metal NP preparation.The widespread adoption of PLAL in scientific and industrial research has...
The high-end laser cutting machine developed and produced by Dongying Lijin Zhancheng Laser Intelligent Manufacturing Company has become popular in overseas markets this spring. This equipment can not only use laser to quickly cut steel, but also freely swing on steel, "showing" beautiful pictures. The laser travels like a paintbrush flying, and the hard steel plate has been hollowed out into be...
IntroductionThe small hole mode swing laser welding has gained increasing recognition due to its ability to bridge gaps, refine microstructures, and enhance the mechanical properties of welds. However, the effects of amplitude, frequency, welding speed, laser beam power, and beam radius on heat flux distribution, melting mode, and three-dimensional temperature field have not been well understood. ...
