High Contrast Sub-Optical-Wavelength Atomic Gratings.

摘要

This report details the scientific progress and accomplishments of the work carried out during the time period of grant number DAADl9-99-1-0033 (311199 - 2128101). The goal of this project was to produce high contrast atomic gratings with a period that is an integer fraction of an optical wavelength. Research was carried out with both a magneto-optical trap (MOT) and an atomic beam. Progress was made in (I) the use of optical masks to create high contrast atomic gratings and gratings with a period that is a fraction of an optical wavelength in a MOT, (2) optimization of an atomic Rb beam, and (3) one dimensional transverse laser cooling of the atomic beam.
