德国电子同步加速器研究中心的一个国际研究小组利用自由电子激光束 ,最近在世界上首次产生了波长只有 1 0 9nm的紫外激光 ,这种纳米激光有望用于对原子结构进行深入分析。这个国际研究小组的科学家来自德国、中国、芬兰等国 ,他们在研究中心 30 0 m长的超导直线对撞机样机上利 An international team of German electron synchrotron research centers, using a free-electron laser beam, recently produced for the first time in the world an ultraviolet laser at a wavelength of only 190 nm, which is expected to be used to further analyze the atomic structure. The international team of scientists from Germany, China, Finland and other countries, they are in the research center 300 m long superconducting linear collider prototype
