Transient laser cooling

Physical Review Letters, 1993
We observed a new type of sub-Doppler cooling that employs neither polarization gradients nor magnetic fields, and involves neither a damping force nor significant diffusive heating. Instead, light shifts combined with optical pumping (OP) to levels not coupled by the laser field gives transient cooling, and steady state is not achieved. The time scale

Laser Cooling

Physics Today, 1987
In the photograph on the opposite page we see a single mercury ion held nearly at rest in an electromagnetic “trap.” Physicists have seen individual atoms before, in arrays imaged by field ion microscopes and more recently by vacuum tunneling microscopes, but what we see here is different.
