对光学糖蜜中原子的激光冷却机理进行了实验研究。通过只研究一维或二维的光学糖蜜，通常的三维几何得到了显着的简化。通过适当的偏振选择，观察到了纯二能级系统的行为以及偏振梯度对多能级原子激光冷却的更为复杂的影响。
The cooling mechanisms for laser cooling of atoms in optical molasses have been investigated experimentally. A significant simplification over the usual three-dimensional geometry has been obtained by studying the optical molasses in one or two dimensions only. By proper choice of polarizations the behavior of a pure two-level system as well as the more complicated effects of polarization gradients on laser cooling of a multilevel atom were observed.
