Simulation of laser-Compton cooling of electron beams for future linear colliders [PDF]

open access: yesPhysical 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

Optical Pumping of TeH+: Implications for the Search for Varying mp/me

open access: yesAtoms, 2018
Molecular overtone transitions provide optical frequency transitions sensitive to variation in the proton-to-electron mass ratio ( μ ≡ m p / m e ).

Λ-enhanced grey molasses on the D2 transition of Rubidium-87 atoms

open access: yesScientific 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.

Laser Cooling of Molecular Anions [PDF]

open access: yesPhysical Review Letters, 2015
We propose a scheme for laser cooling of negatively charged molecules. We briefly summarise the requirements for such laser cooling and we identify a number of potential candidates. A detailed computation study with C$\_2^-$, the most studied molecular anion, is carried out.

Systematic study of tunable laser cooling for trapped-ion experiments

open access: yesNew Journal of Physics, 2023
We report on a comparative analysis of quenched sideband cooling in trapped ions. We introduce a theoretical approach for time-efficient simulation of the temporal cooling characteristics and derive the optimal conditions providing fast laser cooling ...

Plasmon Coupling—The Root Cause of Raman Anomaly and Laser Cooling in Nanocrystal Ge

open access: yesAdvanced Photonics Research, 2023
Laser cooling of matter through anti‐Stokes photoluminescence, where the emitted frequency of light exceeds that of the impinging laser light by virtue of absorption of thermal vibrational energy, has been successfully realized in condensed media, and in

Laser cooling at resonance [PDF]

open access: yesPhysical Review A, 2018
We show experimentally that 3-D laser cooling of lithium atoms is achieved when the laser light is tuned exactly to resonance with the atomic transition. For a theoretical description of this surprising phenomenon we resolve to a full model which takes into account both the entire atomic structure and the laser light polarization.

Low cost fast frequency switching driver for Acousto-Optic Modulators used in laser cooling

open access: yesHardwareX, 2019
In many laser atom cooling experiments, Acousto-Optic Modulators (AOM) are used to modulate a laser beam frequency close to an electronic resonance of the atoms.

Laser patterning assisted devitrification and domain engineering of amorphous and nanocrystalline alloys

open access: yesAIP Advances, 2022
We have investigated laser-patterning and devitrification as a novel method to realize emergent properties in modified regions at the ribbon surface consisting of periodic localized laser spots thermally treated under rapid heating and cooling conditions.

Excellent Ultracold Molecular Candidates From Group VA Hydrides: Whether Do Nearby Electronic States Interfere?

open access: yesFrontiers in Chemistry, 2021
By means of highly accurate ab initio calculations, we identify two excellent ultracold molecular candidates from group VA hydrides. We find that NH and PH are suitable for the production of ultracold molecules, and the feasibility and advantage of two ...
