光学晶体平行表面的抛光是激光光束顺利传输的必要条件。然而，迄今为止，在分子尺度上抛光材料（00-1）表面的方法尚未报道。本文提出了用原子力显微镜扫描有机晶体的纳米抛光方法，并根据表面条件施加适当的载荷。结果表明，在分子尺度上，4-二甲氨基- n -甲基-4-甲酰甲醚（DAST）晶体的（001）面和（00-1）面都是扁平的。因此，我们成功地获得了分子平行表面。
Polishing of the parallel surfaces of an optical crystal is essentially required for smooth transmission of a laser beam. However, a procedure for polishing the (00-1) surface of a material on a molecular scale has not been reported so far. In this paper we have proposed the nano-polishing method of organic crystals by scanning the tip of an atomic force microscope with an appropriate load depending on the surface condition. It has been demonstrated that both the (001) and (00-1) planes of 4-dimethylamino-N-methyl-4-stilbazolium tosylate (DAST) crystal grown by a seed-standing method can be flattened on a molecular scale. Thus, we have successfully obtained molecularly parallel surfaces.
