Sentences with phrase «pulses of ultraviolet light»

Quick pulses of ultraviolet light flash over the mushroom's surface, going through it, and setting off a chemical process that converts a compound similar to cholesterol inside the mushrooms into vitamin D.

And you do all that using very sharp pulses of ultraviolet light, which we generate in my lab.

Not exact matches

Ideally, the electron gains so much energy in the laser field that upon impact with the atom, a much shorter flash of light with very high energy is emitted — an attosecond laser pulse, with a frequency in the ultraviolet - or x-ray regime.

With a light - field synthesizer, a device which can manipulate the properties of visible light and nearby infrared and ultraviolet frequencies, the scientists were able to compose visible light pulses as short as 380 attoseconds.

«We control the below - threshold harmonic light emission by using electromagnetic fields with time - dependent ellipticity, like we have done to the above - threshold high - order harmonics,» said Chang referring to the creation of a 67 - attosecond pulse of extreme ultraviolet light, which earned him international recognition.

In 2008, Eleftherios Goulielmakis at the Max Planck Institute for Quantum Optics in Garching, Germany, and his colleagues generated what were then the shortest pulses of light ever achieved: extreme ultraviolet bursts just 80 attoseconds long.

The availability of intense light pulses in the extreme - ultraviolet range from an alternative source is therefore important to gain a better understanding of the various processes occurring in clusters and other extended systems such as biomolecules exposed to intense XUV pulses.

The new tool will soon be able to generate pulses of high - energy light, with a wavelength of 60 nanometers, in the extreme ultraviolet segment of the spectrum.

These tools, however, produce nothing close to the angstrom - level (tenth of a nanometer) resolution of a new type of microscope that uses femtosecond pulses of extreme ultraviolet light (EUV)-- the same wavelength light to be used for sub-10 nanometer semiconductor lithography.]

Together with Rangaswamy Srinivasan and Samuel E. Blum, for their discovery of pulsed ultraviolet laser surgery, wherein laser light cuts and etches biological tissue by photoablation with minimal collateral damage, leading to healing without significant scarring.
