According to foreign media reports, the US laser manufacturer related company has announced that it has acquired a German company. It is said that Germany's OR Laser has developed a compact and flexible system for the rapid development of laser additive manufacturing applications. This complete additive manufacturing tool includes direct metal deposition (DMD) and selective laser melting (SLM) technology, as well as systems for laser pointer cutting, welding, marking and engraving.
Thomas Merk, executive vice president and general manager of industrial laser systems, said: "The acquisition of Rofin laser has made us a major force in the field of laser machine tools; and the acquisition of OR Laser has provided us with a complementary product line, especially It is our portfolio of solutions for additive manufacturing. In addition, their products will be seamlessly integrated with our current products, as OR Laser's approach is consistent with our company's philosophy of providing a high performance, accurate laser pointer system. To provide unparalleled value and ease of use. We believe this is the key to replacing other traditional manufacturing technologies with lasers. For example, it is these advantages that have made OR Laser a great success in dental and medical device manufacturing."
At the same time, the company has announced that it will invest 50 million euros in 2021 to re-extend its business in Lübeck. It is planned to build a five-story office building and a two- to three-tier production hall, which will nearly double the overall usable area to 13,000 square meters.
Japanese scientists have proposed a new particle acceleration mechanism. Researchers at Osaka University called this laser-driven mechanism "microbubble implosion."
This technique uses a high energy laser pointer pulse to illuminate tiny bubbles of hydride. When the bubbles are squeezed together, high-energy hydrogen ions are released. This approach successfully narrows the nanoscale bubble population to an unprecedented level. The density of the compacted bubbles is equivalent to a cube of sugar weighing more than 220 pounds (about 100 kilograms).
During the blast, the ions move toward a center point at a speed close to half the speed of light. Scientists liken this unique phenomenon to the reverse of the big bang, unlike previous particle acceleration mechanisms.
If scientists can standardize the method, this breakthrough can lead to a surge in the experiment of laser pointer particle acceleration. The researchers say that as a dense source of neutron radiation through nuclear fusion, the concept will be used in a variety of medical applications.
