Optical cooling and trapping of atoms
WebTo this end, we have developed and built a trapping field using an octupole magnetic field, which combines elements of both near-zero fields at the trap center for sub-Doppler cooling, and restoring forces at the boundary to generate cold atoms for long enough times to load an optical dipole trap at high density. WebJul 1, 2015 · Optical Molasses. The atoms while passing through the molasses during their random Brownian motion are subjected to strongly damping viscous forces and dissipate their kinetic energy. Source:...

WebApr 14, 2024 · We report optical trapping of a polyatomic molecule, calcium monohydroxide (CaOH). CaOH molecules from a magneto-optical trap are sub-Doppler laser cooled to 20 (3) μ K in free space and loaded into an optical dipole trap. We attain an in-trap molecule number density of 3 (1) × 10 9 cm − 3 at a temperature of 57 (8) μ K.Trapped CaOH … Radiation pressure is the force that electromagnetic radiation exerts on matter. In 1873 Maxwell published his treatise on electromagnetism in which he predicted radiation pressure. The force was experimentally demonstrated for the first time by Lebedev and reported at a conference in Paris in 1900, and later published in more detail in 1901. Following Lebedev's measurements Nichols and Hull also demonstrated the force of radiation pressure in 1901, with a refined measur…
