全息图是用精细聚焦的离子束在一片30n m厚的薄硅膜上切割出20nm长的极小的裂纹的图案组合而成的。
The holograms were fabricated using a very finely focused ion beam to cut a pattern of extremely small slits just 20 nm across through a thin silicon membrane 30 nm thick.
本文将计算全息图通过紧聚焦飞秒激光脉冲诱导的微爆机制直接记录在玻璃内部，从而得到永久性的计算全息图。
In this thesis, the CGH was recorded directly inside silica glass step by step controlled by PC using a tightly focused femtosecond laser pulses with the mechanism of micro-explosion.
