Generation of a dark hollow beam by a four
... density of cold atom gas from a standard optical molasses[16] is at 1011~1014/cm3 order of magnitude, so this small volume optical dipole trap can realize single atom trap. Many atoms trapping condition can be obtained when illuminated by a laser beam first, which forms an atomic lens optical field ...

How to turn your microscope into a phase contrast microscope
... But the two interfering light sources are not identical. The original source comes through the entire objective. The interfering effect from the disk is passing through a ‘lens’ that replaces the disk, so that the diameter of this beam is much smaller. Now, consider an object in the proper focus poi ...
