The vice president of Nanjing Advanced Laser Technology Research Institute attended the summit and delivered a keynote speech on “Ultrafast laser pointer Micro-Nano Manufacturing Progress and Application”. The ultra-fast laser pointer has a unique ultra-short pulse, which can obtain a very high peak light intensity with a lower pulse energy, so it can solve many processing problems such as high, precise, sharp, hard, and difficult that are difficult to achieve by conventional methods. The surprising processing effect effectively improves the processing quality and processing efficiency, and has a profound impact on industrial processing.
Through direct writing, interference, self-coherence and other technologies, ultrafast lasers can induce structures ranging from nanometers to millimeters on the material surface. These structures give the material surface new properties and open up different application fields. Zhao Quanzhong said that by 2020, the ultrafast laser market will exceed US$1.5 billion, with huge market potential.
Ultrafast laser science is a very young new subject. In recent years, with the breakthrough and commercialization of high-power picosecond, femtosecond laser and fiber ultrafast laser technology, ultrafast laser has moved from laboratory to actual industrial production. application. As the market demand for high-precision processing continues to expand, ultrafast lasers will be more widely used.
The remote robot arm used laser cutting to successfully dismantle the “internal organs” of the nuclear facility. The team used remote green laser pointer cutting technology to dismantle redundant equipment in the nuclear facility. This operation proved the value of combining laser cutting technology with robotics technology and can be more than before. Handle decommissioning tasks in dangerous and confined spaces faster and more effectively. The use of remote laser cutting technology dismantled redundant equipment in the nuclear facility, achieving the world’s first.
The project used a laser combined with a highly flexible remote-controlled robotic arm to successfully cut a large steel dissolving vessel on the Sellafield site. This operation proved the value of combining laser cutting technology with robotics technology, which can handle decommissioning tasks in dangerous and confined spaces faster and more effectively than before. After conducting a feasibility study in 2011, the technology was developed in a collaborative research project jointly funded by the British Innovation Agency in the past four years. Other project partners include TWI, National Nuclear Laboratory, ULO Optics and Laser Optics Engineering.
Sellafield’s future decommissioning team manager said: “The demonstration at Sellafield was very successful and effective. It not only realized a potentially disruptive technology to be tested, tested and verified in a real nuclear decommissioning scenario, but also represented the supply chain. Advantages of collaboration with field operators. This makes research and development funding very successful and may not be achieved.
