Loading CO2 dipole traps
The images below are taken after a time-of-flight. The MOT is loaded
for 2.5 seconds and the trapping fields are switched off, except for
the CO2 laser which is left on through out the cycle.
A 1.8 ms imaging pulse of trapping and repumping light is switched
on after the time indicated. All axes are in mm.
Note that after 25 ms the centre of mass of the MOT will have fallen over
6 mm due to gravity, which is to the left.

This is an image of the trapped atoms 5 seconds after release from
the MOT. The colour scale is the same as on the animation up to 1s.
