LMN World Laser Manufacturing Conference 2023 (hereinafter referred to as “LMN 2023”), which has attracted great attention of the colleagues in the global laser industry, was successfully concluded at Shenzhen Conventional & Exhibition Center (Baoan New Hall) on June 29. The most insightful experts, scholars and industry elites from the United States, Germany, France, Russia, Switzerland, Japan and other countries gathered together to discuss the future development prospects of laser manufacturing technology and draw a bright vision for the laser manufacturing industry with the theme of “Intelligent Laser Manufacturing to Light Up the Future”. The conference lasted for three days, with the first day for a plenary session, and the other two days for several sub-forums and parallel sessions around 3C, carbon peak and neutrality, new energy, energy storage and other hot topics, with attendances of 2063, up by 72% over the previous sessions, and a record high attendance rate. 

This year’s conference received strong support from relevant departments and officials in Guangdong Province, Shenzhen City and Baoan District, as well as the leading figures of the industry. Yuan Baocheng, Vice Chairman of the CPPCC Guangdong Provincial Committee, Wang Shourui, the Secretary of the Baoan District Party Committee, Ying Mingjiong, President of China Optics and Optoelectronics Manufacturers Association, Prof. Gérard Mourou, the 2018 Nobel Laureate in Physics, and Arno Reich, Senior Vice President of Deutsche Messe AG, delivered speeches at the opening ceremony. Fan Dianyuan, Academician of the Chinese Academy of Engineering, Liang Weidong, Director of the Economic Committee of Guangdong Provincial Political Consultative Conference, Wu Shiwen, Deputy Director of Guangdong Provincial Department of Science and Technology, and Chen Longxing, Zhu Yun and Gao Zhan, officials of Baoan District, were present at the forum. 

Shenzhen Laser Industry Contains Unlimited Possibilities, With An Output Value of More Than RMB 10 Billion
In recent years, the laser technology industry has developed rapidly, and laser technology has become an important means of advanced manufacturing, attracting much attention from all walks of life. Ying Mingjiong, President of China Optics and Optoelectronics Manufacturers Association, remarked that Shenzhen is a pioneer in the industrialization of laser technology and laser manufacturing continues to empower the development of the regional economy. The government attaches great importance and renders generous support to the laser industry, and has issued the Action Plan for Cultivating and Developing Laser and Additive Manufacturing Industry Cluster in Shenzhen. The Plan has built a cluster area covering the whole industrial chain of laser and additive manufacturing with Baoan District as the core bearing area, and fostered a number of leading laser enterprises such as Han’s Laser and Max Photonics. The scale of output value exceeds RMB ten billion, which has effectively promoted the industrialization of laser technology.

The Organizer stated that LMN World Laser Manufacturing Conference has always kept its foothold on cutting-edge technology and continuous innovation, and encouraged and supported the innovative application of various new materials, technologies and equipment in the laser field. It hopes through such a high-level international platform as LMN World Laser Manufacturing Conference to showcase the most cutting-edge academic achievements and application solutions, promote the exchange and cooperation between Shenzhen and the global laser field, and further push on the innovative development of the laser industry in Shenzhen and China.

Networking Event Enables Academics to Empower Laser Industry Upgrades
As the industry’s leading conference on technological innovation and application, the LMN this year brought together the world’s best resources and invited top experts and scholars to share innovative technology research and development reports, opening up new ideas for the future development of the laser industry in “production, learning, research and application”.

In the plenary session, Prof. Satoshi Kawata, President of OPTICA, discussed the topic of “How to make three-dimensional nanostructures using optical technology”. Through years of research and practice, he proposed that three-dimensional micro-manufacturing can be achieved using photon polymerization techniques for two-photon absorption and the method of two-photon reduction. However, this drawing and mapping approach, or top-down manufacturing approach, has problems such as expensive laser equipment and too long production time. In response, Prof. Satoshi Kawata proposed a bottom-up approach, inspired by forests, to try to grow silver nanoforests artificially and produce them by self-assembly, self-growth, and self-organization.

Zhong Minlin, Tenured Professor of Tsinghua University, shared his research results on the use of ultrafast laser-induced nanotechnology for efficient hydrogen production by hydrolysis. The nanostructure in the catalyst is the key in the experiment of hydrogen production by hydrolysis. The nanoparticles obtained by general hydrothermal method are not stable, while the nanostructure stability is effectively improved with the use of laser technology, with very high hydrogen-oxygen generation efficiency. In the period, Prof. Zhong Minlin also enumerated the team’s research results on ultrafast laser and nanostructured materials in recent years, such as a lotus leaf type of hydrophobic surface made from any metal surface by using ultrafast laser, and intelligent surface using oil to control surface wettability.

Prof. Shen Ping from South University of Science and Technology of China gave a lecture on “Optical Fiber-Based Technologies and Applications”. Prof. Shen Ping mainly introduced the resonance-resistant fiber with low loss and high speed, and the microstructured fiber which is different from the solid fiber, and shared a series of experiments on fiber loss reduction methods that have been researched with scholars from home and abroad in recent years. He pointed out that optical fiber not only can be used as a transmission tool, but also has many advantages as a sensor, with potential applications in acoustic sensing and biomedical sensors.

Prof. Vyacheslav Trofimov from South China University of Technology presented the development of laser science and technology in Russia, introducing the famous Russian colleges and institutes of laser physics, the scientific research done in the field of lasers in Russia and showcasing some products for laser commercialization.

Prof. Beat Neuenschwander, Vice President of Swiss Society for Optics and Microscopy, presented a video lecture on the topic “Ultrafast Pulsed Laser High Precision Micromachining of Rotational Symmetric Parts by Synchronization of Axes ”. Over the past few years, ultrafast laser has been used to process rotationally symmetric metal cylinders needed for embossing applications. The conventional method uses spiral gravure, namely a slow movement of the machine head in the direction of the rotor shaft. Prof. Beat Neuenschwander introduced a new method that uses a high-end vibrating mirror scanning system to guide the laser beam to pass through the constantly rotating part at a speed of tens of meters per second. The scanning system path is calculated based on the speed of axis rotation, and the axis speed is adjusted according to the pulse spacing in the circumferential direction to achieve synchronized motion of the rotating axes. With this method, the machine can guarantee a few microns of accuracy even if the axis is rotated for hundreds of rounds, making it possible to machine rotationally symmetrical parts with seamless high precision.

At the sub-forum “Laser Technology Application in 3C Electronics Industry Conference 2023”, Prof. Qiu Jianrong from Zhejiang University, Prof. Zhao Quanzhong from Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, Prof. Chen Feng from Xi’an Jiaotong University, and other experts directly focused on the difficulties and pain points in the application of laser technology in 3C electronics process and discussed the topics of laser glass processing technology, ultrafast laser sealing technology and its progress, femtosecond laser micro-nano engineering manufacturing, respectively.

The Trinity of Exhibition, Conference and Competition, Witnessed the High “Light” Moment of the Laser Industry
