When electrons move in molecules or semiconductors, their time scale is unimaginably short. The Swedish German team, including Dr. Jan Vogelsang from the University of Oldenburg, has made significant progress in these ultrafast processes: researchers are able to track the dynamics of electrons released on the surface of zinc oxide crystals using laser pulses with nanoscale spatial resolution and p...
It is reported that the National Institutes of Sciences (INRS) of Canada has developed a camera platform that can achieve cheaper ultra fast imaging through the use of ready-made components, which can be used in various applications.This new device aims to address some of the limitations of current high-speed imaging, including parallax errors and potential damage from pulse illumination. Th...
Researchers from the Fourth Institute of Physics at the University of Stuttgart have demonstrated the feasibility of 3D printed polymer based micro optical devices in harsh laser environments.This study was detailed in the Journal of Optics, outlining the use of 3D printing technology to directly manufacture microscale optical devices on fibers, seamlessly integrating fibers and laser crystals int...
Recently, the research team of the High Power Laser Element Technology and Engineering Department of the Shanghai Institute of Optics and Mechanics, Chinese Academy of Sciences, has made new progress in the study of improving the damage threshold of fused quartz elements through laser cleaning. The study proposes for the first time the use of microsecond pulse CO2 laser cleaning to enhance the dam...
For centuries, people have known that light exhibits wave like behavior in certain situations. When light passes through certain materials, they can change the polarization of light waves (i.e. the direction of oscillation). The core components of optical communication networks, such as optical isolators or photodiodes, utilize this characteristic. This type of component allows light to propagate ...
