Optical cooling and trapping of atoms

WebThe advent of lasers gave birth to various techniques for trapping and manipulating atoms, small particles, and macroscopic objects using optical forces (1–5).An important class of optical manipulation methods, such as Doppler cooling, relies on control over the dynamics of a target by exploiting the dependence of optical pressure on its velocity. WebDec 20, 2024 · The next step toward BEC was to confine atoms in an optical dipole trap. It was known that laser cooling and optical trapping were incompatible if one treated atoms …
