Chu and colleagues: three-dimensional laser cooling and confinement of atoms

Demonstrated three-dimensional viscous confinement and cooling of neutral sodium atoms with counterpropagating laser beams, reporting a temperature near 240 microkelvin.

What is recorded here?

Demonstrated three-dimensional viscous confinement and cooling of neutral sodium atoms with counterpropagating laser beams, reporting a temperature near 240 microkelvin.

Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.

Scientific scope

The record is the exact 1985 Physical Review Letters paper. Earlier radiation-pressure proposals and atomic-beam slowing, later polarization-gradient cooling, magneto-optical traps and Nobel attribution remain separate.
