Optical cooling and trapping of atoms
WebOnce the Doppler cooling limit is reached, diffusive motion of the ultracold atoms is observed [16–19].There is a laser beam configuration—comprising, in three dimensions, three pairs of counter-propagating beams (figure 4.1)—that produces a loose assembly of diffusing ultracold atoms; this is known as optical molasses, so named because the … WebJan 21, 2024 · Scientists at the National Institute of Standards and Technology (NIST) have miniaturized the optical components required to cool atoms down to a few thousandths of a degree Celsius above absolute zero, the first step in employing them on microchips to drive a new generation of super-accurate atomic clocks, enable navigation without GPS, and …

Steven Chu and Carl Wieman Find other … Radiation pressure is the force that electromagnetic radiation exerts on matter. In 1873 Maxwell published his treatise on electromagnetism in which he predicted radiation pressure. The force was experimentally demonstrated for the first time by Lebedev and reported at a conference in Paris in 1900, and later published in more detail in 1901. Following Lebedev's measurements Nichols and Hull also demonstrated the force of radiation pressure in 1901, with a refined measur…
