摘要: 在ICF实验及天体物理的辐射不透明实验中，经常用到多层薄膜靶，激光脉冲气相沉积（PLD）技术是制备多层薄膜靶的较好方法。论述了PLD技术的原理、实验方法和装置的设计，用该方法初步制备了原子级光滑的Cu及Cu/ Fe薄膜。Cu薄膜的均方根粗糙度为0.2nm，Fe薄膜的均方根粗糙度为0.4nm。Abstract: The multifilms targets are often used in the studies of ICF experiment and astrophysical opacity. One of the methods producing these targets is the Pulse Laser Deposition (PLD) technology. In this paper, the principle of PLD technology, experiment method, PLD equipment design and the application in fabrication of the ICF filmtargets have been described in detail. Using PLD method, the Cu films and Cu/Fe films were been produced. The average roughness of Cu films is 0.2nm and Cu/Fe films is 0.4nm. Experiments shown that the equipment and the methods were suitable.
