新华社武汉4月23日电(记者廖君、陈俊经由一根绣花针粗细的光纤,释放出的激光能量可焊接飞机、轮船。记者22日从武汉市获悉,我国首台万瓦连续光纤激光器在光谷问世,中国成为继美国后第二个掌握此技术的国家。
记者在武汉锐科研发中心看到,这台激光器虽然只有约两台冰柜叠加大小,它肚子里却藏着10块“能量方”,每块1100瓦,各产生一条激光束,10条激光束再汇聚到一根光纤,形成合力,最终产生1万瓦的强大能量——这项激光功率合束技术,被美国视为万瓦激光器的核心机密。
据悉,为打破垄断,两位国家“千人计划”专家闫大鹏、李成率队,历时一年研发攻关,终于掌握该技术的自主知识产权。
据了解,在国际上,光纤激光器越来越广泛应用于工业造船、汽车制造、航空航天、军事设备等领域。与传统二氧化碳激光器相比,它的耗电仅为其1/5,体积只有其1/10,但速度快4倍,转换效率高20%,还没有污染。
中国光学学会理事长、中国科学院院士周炳琨认为,过去,我国核心激光器件主要依赖进口,如今取得这一技术国际领先,对我国工业发展将产生巨大推动。
据透露,该技术已纳入明年的国家863计划。闫大鹏表示,年内有信心冲刺2万瓦技术,实现产值1.6亿元。
Xinhua News Agency, Wuhan, April 23 - (Reporter Liu Jun, Chen Jun) via a sewing needle, the thickness of the fiber, the release of the laser energy can be welded aircraft, ships. Reporter 22, learned from the Wuhan City, China's first million watts of continuous fiber lasers come out in Optical Valley, China has become the second after the United States to master the technology.
Reporters research and development center in Wuhan Rui, the laser only about two freezers stack size, 10 energy side is actually hidden in the belly of 1100 watts per block, each generating a laser beam, 10 laser beam then aggregated into a single fiber, and concerted efforts to eventually produce 10,000 watts of powerful energy - the power of this laser beam combiner technology, core secrets of the United States as a million-watt laser.
It is reported that in order to break the monopoly of the two countries "thousands of people plan" expert Yan Dapeng, Li Cheng led the team last year R & D research, finally mastered the technology of independent intellectual property rights.
It is understood that in the international arena, fiber lasers and more widely used in industrial field of shipbuilding, automobile manufacturing, aerospace, and military equipment. Compared with traditional carbon dioxide laser, its power consumption is only 1/5 of the volume is only 1/10, but four times faster, high conversion efficiency of 20%, there is no pollution.
Chairman of the Optical Society of China, Chinese Academy of Sciences Zhou Bingkun the past, our core laser devices are mainly dependent on imports, now made ​​this technology leading international, will be a huge boost for China's industrial development.
According to reports, the technology has been included in next year's National 863 Program. Yan Dapeng, during the year the confidence to sprint 20 000-watt technology, the output value of 160 million yuan.
