In what has been described as the "first communication", Swedish researchers conducted 3D printed quartz glass micro optical devices on the tip of optical fibers. They said that this progress could lead to faster Internet and better connectivity, as well as innovations such as smaller sensors and imaging systems.Scientists from the KTH Royal Institute of Technology in Stockholm have stated that co...
Reducing stray light is one of the main challenges in combustion experiments using laser beams (such as Raman spectroscopy) for detection. By using a combination of ultrafast laser pulses and gated ICCD or emICCD cameras, a time filter can be effectively used to remove bright and constant flame backgrounds. When the signal reaches the detector, these cameras can open electronic shutters within the...
With the explosive growth of data traffic, the market is extremely eager for hybrid photonic integrated circuits that can combine various optical components on a single chip.Silicon is an excellent material for photonic integrated circuits (PICs), but achieving high-performance laser sources in silicon still poses challenges. The monolithic integration of III-V quantum dot (QD) lasers on silicon i...
In the field of modern electronic manufacturing, PCB (printed circuit board) serves as the carrier of electronic components. In its manufacturing process, laser soldering technology has become a key link in PCB electronic manufacturing due to its advantages of high precision, high efficiency, and low thermal impact. This article will explore the application of laser soldering technology and its ma...
The laser additive manufacturing technology of pure copper (Cu) with complex geometric shapes has opened up vast opportunities for the development of microelectronic and telecommunications functional devices. However, laser forming of high-density pure copper remains a challenge.Recently, the forefront of additive manufacturing technology has noticed a joint report by the University of Hong Kong, ...
