物理学家们在纳米尺度下对光进行控制

欧洲的物理学家们揭示了一种可以在远小于激光波长的尺度下对激光的光强分布进行调控的技术。这种技术结合了脉冲成形和近场光学等手段。研究人员认为,这是将激光作为微小尺度下操作物质的工具这一研发进程中一个巨大的进步。

Physicists in Europe have unveiled a new technique that can control the intensity distribution of laser pulses at dimensions that are much smaller than the wavelength of the laser light. The method combines pulse-shaping techniques with near-field optics and the researchers claim that it is a major step forward in the development of laser-based tools for the manipulation of matter on a very small length scales(Nature 446 301).
