Direct Frequency Comb Laser Cooling and Trapping [PDF]

Physical Review X, 2016
Ultracold atoms, produced by laser cooling and trapping, have led to recent advances in quantum information, quantum chemistry, and quantum sensors. A lack of ultraviolet narrow-band lasers precludes laser cooling of prevalent atoms such as hydrogen ...

Laser cooling and trapping of ^{224}Ra^{+}

Physical Review Research, 2023
We report laser cooling and trapping of ^{224}Ra^{+} ions. This was realized via two-step photoionization loading of radium into an ion trap. A robust source for ^{224}Ra atoms, which have a 3.6-day half-life, was realized with an effusive oven ...

Magneto-optical trapping forces for atoms and molecules with complex level structures

New Journal of Physics, 2015
Laser cooling and magneto-optical trapping of molecules typically involves multiple transitions driven by several laser frequencies. We analyze how magneto-optical trapping forces depend on the angular momenta, F _l and F _u , and the g -factors, g _l ...

Critical Limitations in Cryogenic Laser Cooling of Solids: Symmetry‐Related Fluorescence Trapping and Condensation‐Induced Parasitic Heating [PDF]

Advanced Science
Laser cooling of solids to cryogenic temperatures is fundamentally limited by parasitic processes that become critically important below 100 K. While fluoride crystals like Yb3+‐doped LuLiF4 and YLiF4 promise cooling to below 77 K, experimental progress ...

Optical cycling of MgF molecules within the hyperfine states in X(N=1) state [PDF]

Scientific Reports
Achieving laser cooling of molecules necessitates the establishment of a closed optical cycling transition. In contrast to atoms, molecules exhibit additional vibrational and rotational structures, which must be carefully addressed–alongside hyperfine ...

Be+ assisted, simultaneous confinement of more than 15000 antihydrogen atoms [PDF]

Nature Communications
Antihydrogen, the bound state of a positron and an antiproton, is the only pure anti-atomic system ever studied. It is produced exclusively in the laboratory, as it has never been observed in nature.

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 ...

Raman sideband cooling in optical tweezer arrays for Rydberg dressing

SciPost Physics, 2021
Single neutral atoms trapped in optical tweezers and laser-coupled to Rydberg states provide a fast and flexible platform to generate configurable atomic arrays for quantum simulation. The platform is especially suited to study quantum spin systems in

Frequency stabilization of multiple lasers to a reference atomic transition of Rb

Scientific Reports, 2022
Modern atomic clocks based on the interrogation of an atomic transitions in the optical regions require multiple lasers at different wavelength for producing atomic ions, trapping and laser cooling of neutral atoms or atomic ions.
