Recently, Yang Shanglu, a researcher at the Laser Intelligent Manufacturing Technology Research and Development Center of Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, has made new progress in laser welding of the fourth-generation reactor-molten salt reactor structural material Ni-28W-6Cr nickel-based superalloy.The research team applied the high power fiber ...
The application of laser technology has revolutionized the methods of nitrogen fixation, providing a new method for synthesizing ammonia under environmental conditions. Recently, researchers have used commercial carbon dioxide lasers for the first time to disrupt the nitrogen nitrogen triple bond, providing a new green alternative to the Haber Bosch process.It is reported that the international re...
High power optical frequency combs play a crucial role in nonlinear precision spectroscopy, extreme ultraviolet optical frequency comb generation, nuclear atomic clock research, and other fields. Fiber optic femtosecond lasers are the preferred solution for achieving high power optical frequency combs due to their simple structure, stable performance, and easy amplification. However, due to the un...
Recently, American photonics giant Coherent and Japan's Faraday 1867 Holdings signed a Letter of Intent (LOI), with the goal of expanding the manufacturing scale of high-temperature superconducting (HTS) tapes to be widely used in large-scale deployment of nuclear fusion reactors, while also promoting the transformation of green energy. Coherent's excimer laser is expected to be more widely used i...
The latest research led by the University of Surrey shows that alumina (Al2O3) nanoparticles can significantly enhance the lifespan and stability of perovskite solar cells, extending the service life of such high-efficiency energy devices tenfold.Although perovskite solar cells have advantages such as low cost and light weight compared to traditional silicon-based technologies, their commercial po...
