Nov. 24 issue — How do you put an atom to work? Unlike, say, a bowling
ball, which has three holes for your fingers, atoms are hard to get a
handle on. When scientists from Caltech set out to fashion a laser
from a single atom, a big challenge was how to keep the atom still. In
a recent paper in Nature, they describe rigging up an elaborate
contraption of laser beams and mirrors merely to hold a cesium atom in
place long enough—about 100 thousandths of a second—to perform their
experiment.
