| Keywords: Extreme ultraviolet (EUV) frequency comb (6806854303).jpg Artist's conception of JILA's extreme ultraviolet EUV frequency comb The original light source is a pulsed infrared laser which is used to create a train of attosecond-long pulse bursts at EUV wavelengths the bright white spot in the distance Each of the resulting 'harmonics'--strong signals at regular fractions of the original infrared wavelength--has its own set of 'teeth' marking individual frequencies series of adjacent white lines in the foreground creating a frequency comb within each harmonic To prove the new structure exists JILA scientists observed a tooth interacting with argon atoms indicated by the glowing atom symbol in the center foreground See also http //www nist gov/pml/div689/euv_comb cfm www nist gov/pml/div689/euv_comb cfm Credit Baxley/JILA 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/6806854303/ Extreme ultraviolet EUV frequency comb 2012-01-24 12 31 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 N06/6806854303 2016-09-07 02 14 59 United States Government Work Uncategorized 2016 December 20 | ||||
