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…
