摘　　要：利用飞秒激光与铜镍材料作用 ,在不同条件下得到了铜镍材料的分离 ,分离比可达 30 % .分析认为 ,激光等离子体中的自生轴向磁场和环形磁场在同位素的分离过程中可能起着相反的作用 ,二者相互竞争 .不同的磁场构形将对同位素分离产生不同的结果 ,因此 。Separation between copper and nickel has been obtained with femtosecond laser pulses interacting with targets composed of copper and nickel. Analysis shows that the effects of the laser spontaneous axial magnetic field and the laser spontaneous transverse magnetic field are opposite, and there is competition between them in the process of isotope separation. Different magnetic configuration can result in different laser isotope separation. Consequently laser isotope separation could be controlled through controlling laser plasma interaction process.
