It is reported that researchers from TRUMPF in Germany reported research on using dynamic beam shaping of high-power lasers to improve the productivity of hairpin stators, creating opportunities for the electric vehicle industry. Relevant research was published in "PhotonicsViews" under the title "Unlocking opportunities for the EV industry with beam shaping of high-power lasers".The electric vehi...
Ultraviolet spectroscopy plays a crucial role in the study of electronic transitions in atoms and rovibronic transitions in molecules. These studies are crucial for the testing of fundamental physics, quantum electrodynamics theory, determination of fundamental constants, precision measurements, optical clocks, high-resolution spectroscopy supporting atmospheric chemistry and astrophysics, and str...
Introduction and application of a micro optical platform using metasurfacesMetasurfaces are artificial materials that excel in manipulating perception. Due to the fact that metasurfaces can reduce the size of lenses to one thousandth of traditional lenses, they have attracted great attention as optical components for miniaturization of next-generation virtual reality, augmented reality, and LiDAR ...
The ZEUS laser at the University of Michigan recently achieved a breakthrough of doubling the peak power of the strongest laser in the United States through its first 2 quadrillion watt experiment. Although this instantaneous power only lasts for 25 attosecond (one billionth of a second), it exceeds the total power of the global power grid by more than a hundred times.Karl Krushelnick, director of...
Gallium nitride (GaN) vertical cavity surface emitting laser (VCSEL) is a semiconductor laser diode with broad application prospects in various fields such as adaptive headlights, retinal scanning displays, nursing point testing systems, and high-speed visible light communication systems. Their high efficiency and low manufacturing costs make them particularly attractive in these applications.Gall...
