WebJul 13, 2024 · We report laser cooling and trapping of yttrium monoxide (YO) molecules in an optical lattice. We show that gray molasses cooling remains exceptionally efficient for YO molecules inside the lattice with a molecule temperature as low as 6.1 (6) K. WebLaser Cooling of Large Polyatomic Molecules The past several years have been an exciting time in the world of laser-cooled molecules, with diatomic molecules being brought under …
WebAug 5, 2024 · By utilizing light-induced collisions during the laser cooling process, we trap single molecules. The high densities attained inside the tweezer traps have also enabled us to observe in the absence of light molecule-molecule collisions of laser cooled molecules for the first time. WebJan 1, 2024 · In this review, we examine what kinds of molecules can be laser cooled, how to design a suitable cooling scheme, and how the cooling can be understood and …
WebThe transport for laser cooled molecules has several requirements making current available optical transport methods less efficient or infeasible. Room temperature black-body radiation can excite CaF molecules to higher vibrational excited state with opposite parity and limits the lifetime to ~5 seconds. Temperature of the molecules in the ... WebApr 13, 2024 · Laser cooling can chill molecules to just a few microkelvin, but some experiments demand even colder temperatures. One way that researchers propose to …
WebIn this work, we report on creating an optical tweezer array of laser-cooled calcium monofluoride molecules. This platform has also allowed us to observe ground-state collisions of laser-cooled molecules both in the presence and absence of near-resonant light.
