脉宽为120fs、能量为7mJ、红外激光与固体硼(B)靶相互作用,在靶的法线方向利用铜作为沉积基片生长了一层B膜。利用二次离子质谱方法分析了B在基片上的同位素分离情况,测量结果表明在超短激光等离子体相互作用过程中产生的自生磁场对B同位素产生分离作用,一级浓
The pulse width is 120 fs and the energy is 7 mJ. The infrared laser interacts with the solid boron (B) target and grows a layer of B film using copper as the deposition substrate in the normal direction of the target. The secondary ion mass spectrometry method was used to analyze the isotope separation of B on the substrate. The measurement results show that the autogenous magnetic field generated during the interaction of ultrashort laser plasma has a separation effect on the B isotope,
