Abstract | |
From the very beginning of the development of atomic motion control techniques using the radiation pressure force, a variety of applications have been suggested and implemented. Of all these, atomic trapping techniques and the development of spatial structures using cold atoms deserves special attention due to its potential application to surface deposition such as lithography. In the present work, we perform a study on atomic beams and their deceleration and spatial compression. We also perform numerical studies and present experimental observation of the realization of spatial ring structures in atomic beams, verifying its factibility, and we study the compression of such ring-shaped structures with application in atomic nanolithography as the ultimate goal.
