Recently, Professor Nie Mingming from the Key Laboratory of Fiber Optic Sensing and Communication at the School of Information and Communication Engineering, University of Electronic Science and Technology of China, in collaboration with the University of Colorado Boulder, published a research paper titled "Cross polarized stimulated Brillouin scattering empowered photonics" in the top internation...
Organic solid-state lasers (OSLs) are expected to achieve widespread applications due to their flexibility, tunability, and efficiency. However, they are difficult to manufacture and require over 150.000 possible experiments to find successful new materials, and discovering them will be a work of several lifetimes. In fact, according to data from the University of Toronto in Canada, only 10-20 new...
Recently, the team from the State Key Laboratory of Intense Field Laser Physics, Shanghai Institute of Optics and Mechanics, Chinese Academy of Sciences found that the third-order harmonics induced by air filamentation of high repetition rate femtosecond lasers have significant self jitter. To solve this bottleneck problem, a solution based on an external DC electric field was proposed, which sign...
Aluminum alloy has unique advantages such as lightweight, high strength, and excellent corrosion resistance, and is highly favored in the aerospace manufacturing field. Laser Coaxial Fusion Additive Manufacturing (LCWAM) adopts beam shaping technology, which uses wire as the deposition material to melt and stack layer by layer. Compared to traditional side axis wire feeding technology, laser coaxi...
Of the three primary stepper motor designs — permanent magnet, variable reluctance, and hybrid — hybrid stepper motors are arguably the most popular in industrial applications, combining the best performance characteristics of permanent magnet and variable reluctance types.Hybrid stepper motors are constructed with a rotor made of two sections, or cups, with a permanent magnet between ...
