Academicians, Academician Du Xiangfan and Vice Mayor Zhang Wei made speeches respectively at the opening ceremony, and Academician Lv Yue-guang presided over the seminar. More than 300 professional researchers, teachers and students, and senior executives from all over the country attended the conference. And laser manufacturing network editors were invited to attend the meeting.
Academician Jin Guofan highly affirmed that high-power and high-energy laser technology is playing an increasingly important role in national defense and industry. The development of high-power and high-energy laser technology and its applications has led to the development of relevant disciplines and the study of difficult theories, technologies and engineering in the field Technical issues, will greatly promote the development of high-power high-energy laser applications.High-power high-energy laser involves a lot of basic research topics, will lead to strong laser theory and basic optical level.This seminar will be devoted to discuss and solve these problems, I believe the exchange results of the General Assembly will greatly promote the development and application of high-power and high-energy laser technology in our country.
Du Xiangfan academician speech
In his speech, Academician Duxiang Xiang said that the generation, transmission and application of high-power high-energy laser are one of the important development directions of modern laser technology and optical engineering and involve a series of engineering and technical problems that are extremely difficult in physics and physics. In the laser has been attached great importance to two aspects, one is the laser fusion, and the other is a high-energy laser, are 60 years of the last century has been started, it has been 50 years, countless laser predecessors laid a solid foundation for us The future belongs to the young generation, experts and scholars engaged in the research of high power and high energy laser technology and application in China today are the sustenance of China's future laser business, hoping to make frank exchanges with relevant experts and scholars and promote common cooperation. China's high-power high-energy laser technology to make its due contribution.
Weihai Vice Mayor Zhang Wei speech
Wei Wei, Vice Mayor of Weihai, warmly welcomed many experts and scholars to visit Weihai during his speech. The event was held in Weihai and was a blessing and happy event for Weihai.He said that in recent years, Weihai has taken the laser industry as a key industry nurture in the high zone Planning and construction of the electronic information and intelligent manufacturing industry park, the introduction of the Ministry of Industry and electronic information technology research center and other state-level high-end platform, have a good industrial base, support platform and personnel advantages .Weihai also has a laser benchmark - Haifu photon Technology Co., Ltd .. He stressed that Weihai is a livable city recognized by the United Nations and owns 10 universities including Harbin Institute of Technology and Shandong University Weihai and is a good place for scientific research and innovation, and hopes to take this seminar as an opportunity to build up a partnership with you Academician and expert communication and exchange and cooperation and development platform to jointly promote the application of advanced high-power and high-energy laser technology in Weihai.
The first report was "advanced high-power semiconductor laser technology and application" lectured by academician Wang Lijun of Changchun Institute of Optics and Optoelectronics. He introduced the development of high-energy semiconductor lasers, with the current conversion efficiency of over 70%, which is the most promising prospect Of the laser light source.He said that the current restrictions on the promotion of the application of semiconductor lasers is mainly the beam quality and brightness is not enough, not as good as fiber lasers for cutting, but the future of semiconductor lasers in the laser repair, the possibility of welding is very large. He saw the semiconductor laser application market in recent years, gradually accelerating growth, I believe soon will play an important role in the national economy.
Academician Liu Zejin of National University of Defense Technology reported, "Progress and Analysis of High-Power Fiber Laser Research." He pointed out that fiber lasers have the advantages of good single-fiber beam quality, high conversion efficiency, flexible processing operation and compact structure, etc. Currently, Mold abroad has done 20,000 watts, and multi-mode also has more than 100,000 watts class. The current study of high-power fiber lasers, National Defense Science and Technology, Tsinghua University, Xi'an Institute of Optical, China Institute of Engineering Physics , Shanghai Institute of Optics and Fine Mechanics, Tianjin University, etc. He further reported on the new achievements of the National Defense Science and Technology Research Group.
He gave a speech entitled "High Power Fiber Laser Spectroscopy Synthesis." He introduced that high-energy solid-state laser weapons are projects that all countries are making great efforts to develop, including Raytheon, Lockheed Martin, Germany MBDA, Rhine Metal, long history of China, etc. To explore the optimal spectral synthesis technology is one of the key points to study high-power laser. In 2015, Zhongwuyuan successfully expanded the synthesis channel to 10 channels and took the lead in realizing the output of 10,000-watt spectral synthesis in China.
In the afternoon of the same day, December 10, a total of more than 20 reports of six special conferences were held, including Wu Bi, Air Force Institute of Equipment, Jinyu Qi, Dalian Institute of Chemical Physics, CAS Zhao Xueqing, Northwest Institute of Nuclear Technology, Fan Zhongwei, Institute of Physics, Chinese Academy of Sciences Lin Wenxiong, Zhongyuan Institute of Laser Fusion Zheng Weiguo, Chinese Academy of Sciences Shanghai Institute of Light cold Yuxin, Sichuan University Feng Guoying, Chinese Academy of Sciences Institute of Physics Wei Zhiyi, Peking University Zhang Zhigang and other experts and scholars deduced wonderful report.
This advanced advanced high-power and high-energy laser technology and application seminar is a high-level laser technology seminar jointly developed by China Institute of Optics and Engineering with renowned national laser research institutes, which is of positive significance for promoting the latest laser achievement exchange and exhibition. The demand for laser technology in our country is rapidly increasing, so it is urgent to make breakthroughs in the research of laser core technology. Therefore, the convening of this conference enables most of our laser researchers to recognize the current trend of laser technology and understand the current situation of our laser in the world The level of development, one after another gratifying results announced, greatly encouraged the confidence of researchers, I believe that China's laser high-end technology research and development work will be made greater progress!
