Laser-Assisted Evaporative Cooling of Anions [PDF]

open access: yesPhysical Review Letters, 2019
We report the first cooling of atomic anions by laser radiation. O^{-} ions confined in a linear Paul trap were cooled by selectively photodetaching the hottest particles. For this purpose, anions with the highest total energy were illuminated with a 532 nm laser at their maximal radial excursion.
