An Optical Centrifuge

Strong non-resonant laser fields produce AC Stark shifts that can approach 25-meV per atom in the molecule. The large Stark shift gives us a handle to control the molecule. I will describe an experiment where a molecular beam of CS2 or I2 molecules is focussed by a 1.06 or 10.6 micron laser beam. The focal length of the "molecular lens" was about 500-microns. I will also describe an optical centrifuge. In it, we spin Cl2 molecules until they are rotating so fast that the bond snaps because of the centrifugal force.
