Recently, the German research institution Fraunhofer ILT team is collaborating with the Department of Optical Systems Technology (TOS) at RWTH Aachen University to develop a testing system aimed at studying complex laser beam profiles using a new platform. This platform can construct customized beam profiles for laser powder melting (PBF-LB) 3D printing, thereby improving part quality, process sta...
In 2017, the detection of gravitational waves generated by the merger of binary neutron stars marked a significant breakthrough in physics. These waves reveal important information about the universe, from the origin of short gamma ray bursts to the formation of heavy elements.However, capturing gravitational waves from the merged residue remains a challenge as these waves avoid the detection rang...
According to reports, British scientists will build the world's largest power laser. They hope that this £ 85 million (approximately $103 million) device can accelerate the use of nuclear fusion and potentially obtain clean energy, which is inexhaustible.According to the report, the "Vulcan" 20-20 laser will be built in Havel, Oxfordshire, and it will produce a laser brightness that is 24 t...
Professor Zhang Huaijin and Yu Haohai from the Institute of Crystal Materials of Shandong University (the State Key Laboratory of Crystal Materials) proposed a spatial harmonic modulation strategy, which realizes the phase matching conditions that can be manipulated artificially in the new quartz crystal, and realizes the effective frequency doubling within the VUV range. The relevant research is ...
The laser driven particle accelerator on silicon chips was created by two independent research groups. With further improvements, this dielectric laser accelerator can be used in medicine and industry, and even in high-energy particle physics experiments.Accelerating electrons to high energy is usually accomplished over long distances in large and expensive facilities. For example, the electron ac...
