Scientists from the Stanford National Accelerator (SLAC) laboratory of the US Department of Energy have revealed new information about the photoelectric effect using attosecond pulses: the delay time of photoelectric emission is as long as 700 attosecond, far exceeding previous expectations. The latest research challenges existing theoretical models and helps to reveal the interactions between ele...
Researchers at the National Institute of Information and Communication Technology in the United States have invented a new structure of a superconducting strip photon detector that can achieve efficient photon detection even in wide strips, and have successfully developed the world's first superconducting wide strip photon detector.The band width of the detector is more than 200 times that of trad...
Optical resolution "photoacoustic microscope is a new biomedical imaging technology, which can be used in the research of cancer, diabetes, stroke and other diseases. However, insufficient sensitivity has always been a long-term obstacle to its wider application.According to Maims Consulting, a research team from City University of Hong Kong (CityU) has recently developed a multispectral, ultra-lo...
At last month’s LASER World of Photonics exhibition in Munich, Germany, industrial solutions and laser giant Trumpf presented a new materials processing laser system solution specified to improve welding processes.The system combines several sensors that monitor all process steps during laser welding. An integrated AI quality control system checks the weld seams, for example, and OCT (optical cohe...
The emergence of smart glasses is a product of the new era of technology and is widely regarded as a key technology for the future. However, due to technological limitations, applications are also restricted. In addition, if the size of high-efficiency luminescent pixels is reduced to the wavelength of emitted light, their use will also be limited by traditional optics.Now, physicists at Julius-Ma...
