该项目的短期目标是探索和利用原子上的光力,特别是亚稳态氦原子,这种力来自于对原子和光场之间动量交换的改进控制。这种改进的控制源于精心安排的、快速的、连贯的吸收序列,随后是使用非色光的受激发射。更长期的计划是利用这些巨大的力可以产生的极冷且密度极高的氦样品。在考虑的可能性列表中,利用高内能进行光刻纳米制造,利用自组装单层来制作抗蚀剂。
英文摘要
The short term goal of this project is to explore and exploit optical forces on atoms, particularly metastable helium atoms, that derive from improved control of the momentum exchange between the atoms and the light field. This improved control arises from carefully orchestrated, rapid, coherent sequences of absorptions followed by stimulated emissions using non-chromatic light. The longer term plans are for applications of the extremely cold and dense sample of helium that can be produced with these large forces. High on the list of possibilities under consideration is exploitation of the high internal energy for nanofabrication by lithography using self-assembling monolayers to pattern a resist.
