我国首台万瓦光纤激光器在武汉问世

　　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。近日从武汉市获悉，我国首台万瓦连续光纤激光器在武汉问世，中国成为继美国之后第二个掌握此项技术的国家。
       这台激光器虽然只有约两台冰柜叠加大小，但它肚子里却藏着10块“能量方”，每块1100瓦，各自产生一条激光束，10条激光束再汇聚到一根光纤上，形成合力，最终产生1.1万瓦的强大能量。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。
        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，终于掌握了该项技术。在国际上，光纤激光器越来越广泛地应用于工业造船、汽车制造、航空航天、军事设备等领域。与传统的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，但速度却快4倍，转换效率高20％，还没有污染。
        该项技术目前已纳入明年的国家863计划。技术团队年内还将研发2万瓦技术，实现产值1．6亿元目标。
