Laser processing is a relatively emerging non-contact processing method that utilizes the high energy of a beam of light to interact with materials and instantly vaporize or change their properties to achieve the expected manufacturing effect. It has gradually been promoted and applied in China in the past 20 years. Due to the different types, pulse widths, and wavelengths of laser generators, the...
Recently, according to the journal Nature Nanotechnology, a team from the California Institute of Technology reported that they have constructed a metasurface covered with micro adjustable antennas that can reflect incident light beams: one beam of light enters and multiple beams of light exit, each with a different frequency and propagating in a different direction. This is a new method for proce...
Light can calculate functions during propagation and interaction with structured materials, with fast speed and low energy consumption. The use of all optical neural networks for general computing requires an optical activation layer with nonlinear dependence on the input. However, existing optical nonlinear materials either have slow speeds or very weak nonlinearity at the level of natural light ...
Recently, the UK's national synchrotron "Diamond Light Source" announced an investment of nearly £ 520 million ($648.3 million) to implement three new flagship beam lines and upgrade existing beam lines. This comprehensive upgrade will be delivered by 2030.The Department for Science, Innovation, and Technology and the biomedical charity Wellcome jointly approved the facility upgrade project,...
Just ten years ago, fiber laser cutting machines were considered experts in thin plates. The stores quickly realized that they had to invest in them to compete, at least by reducing their instrument materials. For high-quality sheet metal cutting, CO2 laser is still the way to go. Of course, fiber lasers can cut thicker blanks, but the quality is not very good, and their speed advantage almost dis...
