国内自主研发首套碳化硅晶锭激光剥离设备投产

In order to successfully 3D print metal parts to meet the strict specifications required by many industries, it is necessary to optimize process parameters, including printing speed, laser power, and layer thickness of deposited materials.However, in order to develop additive manufacturing process diagrams that ensure these optimal results, researchers have to rely on traditional methods, such as ...

As humanity enters a new era of computing, new small tools are needed to enhance the interaction between photons and electrons, and integrate electrical and photon functions at the nanoscale. Researchers have created a novel III-V semiconductor nanocavity that can limit light below the so-called diffraction limit, which is an important step towards achieving this goal.In the journal Optical Materi...

Fiber laser, with its simple structure, low cost, high electro-optical conversion efficiency, and good output effect, has been increasing in proportion in industrial lasers year by year. According to statistics, fiber lasers accounted for 52.7% of the industrial laser market in 2020.According to the characteristics of the output beam, fiber lasers can be classified into two categories: continuous ...

SpaceX President Gwynne Shotwell stated at a meeting on Tuesday that the company has started selling satellite lasers for fast space communication to other satellite companies.SpaceX's thousands of Starlink satellites in low Earth orbit use inter satellite laser links to transmit data to each other in space at the speed of light, so that the network can provide more extensive Internet coverage wo...

Zhang Jun, an academician team of Beijing University of Technology, pioneered the on chip spectral multiplexing perception architecture, and independently developed the first 100 channel megapixel hyperspectral real-time imaging device in the world, creating the world's highest light energy utilization rate. On November 7, the team's relevant achievements were published in the journal Nature, and ...
