Laser cutting is a type of metal processing. In industry, there are three main cutting methods: mechanical cutting, thermal cutting, and a set of high-precision cutting methods. Laser technology belongs to the third category. The cutting in this method occurs due to the influence of the laser beam on the product. In fact, it is the molten metal produced by rapid pulse point melting and then blowin...
The foundation of offshore wind turbines, port protection systems, steel sheet piles, river barriers, water gates, and even pipelines can all be directly processed in water. Another application area is the dismantling of abandoned nuclear reactors, in which case laser technology can gently dismantle steel structures underwater while minimizing the dissolution of radioactive materials.The ocean, wh...
Us researchers report 8.1 μm wavelength quantum cascade laser (QCL) grown on silicon (Si) by MOCVD [S. Xu et al., Applications. Physics Letters, v123, p031110, 2023]. "There are no previous reports of QCL growth on silicon substrates by metal-organic chemical vapor deposition (MOCVD)," commented the team from the University of Wisconsin-Madison, the University of Illinois at Urbana-Champaign an...
On the first day of the 2025 Paris Air Show, the UK government announced a £ 250 million investment to support sustainable aerospace programs, with £ 48.5 million earmarked for funding additive manufacturing projects led by Airbus and GKN Aerospace. Among them, £ 10.5 million will be injected into the GKN Integrated System Level Aerospace Structure Assembly (ISLAA) program, with the aim of utilizi...
The quantum cascade laser (QCL) market is maintaining stable growth globally. This trend is mainly due to the continuous advancement of technology, the expanding scope of industrial applications, and the increasing demand in multiple fields such as national defense, healthcare, and scientific research. In 2023, the market size has reached $416.85 million and is expected to grow to $617.93 million ...
