Atom cooling and trapping by disorder [PDF]
, 1998 We demonstrate the possibility of three-dimensional cooling of neutral atoms by illuminating them with two counterpropagating laser beams of mutually orthogonal linear polarization, where one of the lasers is a speckle field, i.e. a highly disordered but

Laser cooling of new atomic and molecular species with ultrafast pulses
, 2003 We propose a new laser cooling method for atomic species whose level structure makes traditional laser cooling difficult. For instance, laser cooling of hydrogen requires single-frequency vacuum-ultraviolet light, while multielectron atoms need single ...

Two-photon and EIT-assisted Doppler cooling in a three-level cascade system [PDF]
, 2006 Laser cooling is theoretically investigated in a cascade three-level scheme, where the excited state of a laser-driven transition is coupled by a second laser to a top, more stable level, as for alkali-earth atoms.

Photodetachment and Doppler laser cooling of anionic molecules
New Journal of Physics, 2018 We propose to extend laser-cooling techniques, so far only achieved for neutral molecules, to molecular anions. A detailed computational study is performed for ${{\rm{C}}}_{2}^{-}$ molecules stored in Penning traps using GPU based Monte Carlo simulations.

Laser Cooling and Trapping of Rare-Earth-Doped Particles
Applied Sciences, 2022 This review focuses on optical refrigeration with the anti-Stokes fluorescence of rare-earth (RE)-doped low-phonon micro- and nanocrystals. Contrary to bulk samples, where the thermal energy is contained in internal vibrational modes (phonons), the ...

Λ-enhanced grey molasses on the D2 transition of Rubidium-87 atoms
Scientific Reports, 2018 Laser cooling based on dark states, i.e. states decoupled from light, has proven to be effective to increase the phase-space density of cold trapped atoms.

Cooling devices in laser therapy
Journal of Cutaneous and Aesthetic Surgery, 2016 Cooling devices and methods are now integrated into most laser systems, with a view to protecting the epidermis, reducing pain and erythema and improving the efficacy of laser. On the basis of method employed, it can be divided into contact cooling and non-contact cooling.

Three-dimensional model of small signal free-electron lasers
Physical Review Special Topics. Accelerators and Beams, 2011 Coherent electron cooling is an ultrahigh-bandwidth form of stochastic cooling which utilizes the charge perturbation from Debye screening as a seed for a free-electron laser.
