Laser cooling of solids [PDF]

open access: yesReports on Progress in Physics, 2010
Parallel to advances in laser cooling of atoms and ions in dilute gas phase, which has progressed immensely, resulting in physics Nobel prizes in 1997 and 2001, major progress has recently been made in laser cooling of solids. I compare the physical nature of the laser cooling of atoms and ions with that of the laser cooling of solids.

SYMPATHETIC COOLING OF LITHIUM BY LASER-COOLED CESIUM [PDF]

open access: yesLaser Spectroscopy, 2002
We present first indications of sympathetic cooling between two neutral, optically trapped atomic species. Lithium and cesium atoms are simultaneously stored in an optical dipole trap formed by the focus of a CO$_2$ laser, and allowed to interact for a given period of time. The temperature of the lithium gas is found to decrease when in thermal contact

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 to Quantum Degeneracy [PDF]

open access: yesPhysical Review Letters, 2013
We report on Bose-Einstein condensation (BEC) in a gas of strontium atoms, using laser cooling as the only cooling mechanism. The condensate is formed within a sample that is continuously Doppler cooled to below 1\muK on a narrow-linewidth transition. The critical phase-space density for BEC is reached in a central region of the sample, in which atoms ...

Operation of an optical in-well-pumped vertical-external-cavity surface-emitting laser [PDF]

open access: yes, 2006
We report the operation of an optical in-well-pumped vertical-external-cavity surface-emitting laser. The laser delivers 1 W at 855 nm and is pumped with a cost-effective fiber-coupled laser diode emitting at 806 nm.

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-induced rotation and cooling of a trapped microgyroscope in vacuum [PDF]

open access: yes, 2013
This work was supported by the UK Engineering and Physical Sciences Research Council (EPSRC grant numbers: EP/J01771X/1 and EP/G061688/1)Quantum state preparation of mesoscopic objects is a powerful playground for the elucidation of many physical ...

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 ...
