WebLaser cooling of cesium atoms in gray optical molasses down to 1.1 μK (PDF) Laser cooling of cesium atoms in gray optical molasses down to 1.1 μK C. Salomon and Laurent Cognet - Academia.edu Academia.edu no longer supports Internet Explorer. WebA low-pressure vapor of cesium atoms is stored in a glass cell whose volume is 58 cm 3. Cooling laser light λ = 852 nm is injected into the cell by optical fibers and is recycled by multiple reflections from the walls of the cylinder. The technique used in this experiment greatly simplifies the generation of laser-cooled atoms.
WebWe exploit the magnetic field dependence of gray molasses cooling to compensate stray magnetic fields in our UHV chamber. Our method is very intuitive and fast. We use it to achieve record breaking sub-Doppler temperature below 8 μK after gray molasses cooling of 39 K. Appl. Sci. 2024, 11 (21), 10474 Crossed optical dipole trap filled with cesium.

WebWe report on the efficient gray molasses cooling of sodium atoms using the D2 optical transition ′ = 2i and F′ = 3i in the excited state 32P 3/2, this atomic transition is effective for the gray molasses cooling mechanism. Using this cooling technique, the atomic sample in F = 2 ground manifold is cooled from 700 µK to 56 µK in 3.5 ms. i say a little prayer 歌詞 日本語WebmK were found. We show here that cesium six-beam gray molasses can provide temperatures as low as 1.160.1 mKat low atomic density.
