optical molasses

optical molasses n. Physics a field of strong laser light that exerts a damping force on the motion of free atoms in it, thereby cooling them to a very low temperature; (also) a system of atoms that has been confined and cooled by such a field.

ΚΠ

1985 S. Chu et al. in Physical Rev. Lett. 55 48/2 An estimate of the confinement time can be obtained by the observation that the motion of atoms in a viscous fluid of photons (‘optical molasses’) is analogous to diffusion in classical Brownian motion.

1996 Sci. Amer. Jan. 22/1 They directed the stream through ‘optical molasses’—a laser beam set just below the frequency at which chromium atoms resonate like struck bells—which slowed the atoms.
