The last few years have seen rapid progress in the application of laser cooling to molecules.
In this review, we examine what kinds of molecules can be laser cooled, how to design a …

A diversity of experimental techniques has been developed over the last 25 years to create
samples of molecular gases at temperatures close to the Absolute Zero—here we consider …

Precision measurements in molecules have advanced rapidly in recent years through
developments in techniques to cool, trap, and control. The complexity of molecules makes …

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 toward quantum …

As a heavy molecule, barium monofluoride (BaF) presents itself as a promising candidate for
measuring permanent electric dipole moment. Here we report the realization of three …

Currently, there is great interest in laser cooling of barium monofluoride (BaF) molecules for
precision tests of fundamental symmetries. We use high-resolution absorption spectroscopy …

Aluminium monofluoride (AlF) is a promising candidate for laser cooling and trapping at high
densities. We show efficient production of AlF in a bright, pulsed cryogenic buffer gas beam …

We report on a cycling scheme for Doppler cooling of trapped OH+ ions using transitions
between the electronic ground state X 3Σ–and the first excited triplet state A 3Π. We have …

We demonstrate one-dimensional Doppler cooling of a beam of buffer-gas-cooled barium
monofluoride (BaF) molecules. This represents a key step towards further cooling and …

We demonstrate optical cycling and laser cooling of a cryogenic buffer-gas beam of calcium
monohydride (CaH) molecules. We measure vibrational branching ratios for laser cooling …
