Blue-Detuned Magneto-Optical Trap [PDF]
Physical Review Letters, 2018 We present the properties and advantages of a new magneto-optical trap (MOT) where blue-detuned light drives `type-II' transitions that have dark ground states. Using $^{87}$Rb, we reach a radiation-pressure-limited density exceeding $10^{11}$cm$^{-3}$ and a temperature below 30$ $K.

Magneto-optical trapping of barium [PDF]
Physical Review A, 2009 First laser cooling and trapping of the heavy alkaline earth element barium has been achieved based on the strong 6s$^2$ $^1$S$_0$ - 6s6p $^1$P$_1$ transition for the main cooling. Due to the large branching into metastable D-states several additional laser driven transitions are required to provide a closed cooling cycle. A total efficiency of $0.4(1)

Nature Communications, 2021 Here, the authors discuss state-changing inelastic collisions between rubidium Rydberg and ground state atoms. They employ high-resolution magneto-optical trap recoil-ion momentum spectroscopy to measure the distribution of the final states.

Non-Reciprocal Amplification of Light Using Cold Atoms Coupled to an Optical Nanofiber [PDF]
EPJ Web of Conferences, 2022 Optical nanofibers realized as the waist of tapered silica fibers can be used to trap and optically interface laser-cooled atoms. Building on this system, we experimentally show a novel scheme for the nonreciprocal Raman amplification of light.

A method for loading magneto-optical trap in an ultrahigh vacuum environment
AIP Advances, 2023 We have developed a method that enables loading a magneto-optical trap (MOT) in an ultrahigh vacuum environment. Nearly 1.0 × 108 atoms of 87Rb are trapped in the MOT at ∼2.0×10−10 Torr base pressure in the chamber.

Magneto-optical trapping of holmium atoms [PDF]
Physical Review A, 2014 We demonstrate sub-Doppler laser cooling and magneto-optical trapping of the rare earth element Holmium. Atoms are loaded from an atomic beam source and captured in six-beam $ _+ - _-$ molasses using a strong $J=15/2 \leftrightarrow J=17/2$ cycling transition at $ =410.5 \rm nm$.

Blue-Detuned Magneto-optical Trap of Molecules
Physical Review Letters, 2023 Direct laser cooling of molecules has reached a phase space density exceeding 10$^{-6}$ in optical traps, but with rather small molecular numbers. To progress towards quantum degeneracy, a mechanism is needed that combines sub-Doppler cooling and magneto-optical trapping (MOT) to facilitate near unity transfer of ultracold molecules from the MOT to a ...

Laser-induced thermal source for cold atoms
Scientific Reports, 2022 We demonstrate a simple and compact approach to laser cool and trap atoms based on laser-induced thermal ablation (LITA) of a pure solid granule. A rapid thermalisation of the granule leads to a fast recovery of the ultra-high vacuum condition required ...
