Simulation of laser-Compton cooling of electron beams for future linear colliders
Physical Review Special Topics. Accelerators and Beams, 2001 We study a method of laser-Compton cooling of electron beams for future linear colliders. Using a Monte Carlo code, we evaluate the effects of the laser-electron interaction for transverse cooling. The optics with and without chromatic correction for the

Spectroscopic characterization of aluminum monofluoride with relevance to laser cooling and trapping [PDF]
Physical Review A, 2019 Here we report on spectroscopic measurements of the aluminum monofluoride molecule (AlF) that are relevant to laser cooling and trapping experiments. We measure the detailed energy level structure of AlF in the X$^1\Sigma^+$ electronic ground state, in ...

Laser cooling with intermediate state of spin–orbit coupling of LuF molecule
Scientific Reports, 2023 This work presents a theoretical study of the laser cooling feasibility of the molecule LuF, in the fine structure level of approximation. An ab-initio complete active space self-consistent field (CASSCF)/MRCI with Davidson correction calculation has ...

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.

Laser Cooling of Radium Ions [PDF]
Physical Review Letters, 2019 The unstable radium nucleus is appealing for probing new physics due to its high mass, octupole deformation and energy level structure. Ion traps, with long hold times and low particle numbers, are excellent for work with radioactive species, such as radium and radium-based molecular ions, where low activity, and hence low total numbers, is desirable ...

Robust polarization gradient cooling of trapped ions
New Journal of Physics, 2022 We implement three-dimensional polarization gradient cooling (PGC) of trapped ions. Counter-propagating laser beams near 393 nm impinge in lin ⊥ lin configuration, at a frequency below the S _1/2 to P _3/2 resonance in ^40 Ca ^+ .

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 ...

Creation of a Bose-condensed gas of 87Rb by laser cooling [PDF]
Science, 2017 Packing rubidium into quantum degeneracy When atomic gases, such as those of alkali elements, are cooled to very low temperatures, they can reach a state of quantum degeneracy, where their quantum nature comes to the fore.
