Keywords: 1 Million Ytterbium Atoms Illuminated by a Blue Laser (5940299799).jpg This photo shows about 1 million ytterbium atoms illuminated by a blue laser in an experimental atomic clock that holds the atoms in a lattice made of intersecting laser beams The photo was taken with a digital camera through the window of a vacuum chamber NIST is studying the possible use of ytterbium atoms in next-generation atomic clocks based on optical frequencies which could be more stable and accurate than today's best time standards based on microwave frequencies Credit Zeb Barber/NIST Disclaimer Any mention of commercial products within NIST web pages is for information only; it does not imply recommendation or endorsement by NIST Use of NIST Information These World Wide Web pages are provided as a public service by the National Institute of Standards and Technology NIST With the exception of material marked as copyrighted information presented on these pages is considered public information and may be distributed or copied Use of appropriate byline/photo/image credits is requested https //www flickr com/photos/usnistgov/5940299799/ 1 Million Ytterbium Atoms Illuminated by a Blue Laser 2011-07-15 11 21 https //www flickr com/people/63059536 N06 National Institute of Standards and Technology PD-USGov National Institute of Standards and Technology https //flickr com/photos/63059536 N06/5940299799 2016-09-07 02 34 10 United States Government Work Uncategorized 2016 October 20 |
