JILA Scientists Confirm First 'Frequency Comb' to Probe Ultraviolet Wavelengths
February 1, 2012
Physicists at JILA have created the first "frequency comb" in the extreme, ultraviolet band of the spectrum--high-energy light less than 100 nanometers in wavelength. Laser-generated frequency combs are the most accurate method available for precisely measuring frequencies, or colors, of light. The new tool can aid in the development of nuclear clocks based on ticks in the nuclei of atoms, and measurements of previously unexplored behavior in atoms and molecules.
National Institute of Standards and Technology (NIST)
The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2016, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards. NSF also awards about $626 million in professional and service contracts yearly.
