Sending a relativistic beam of electrons through a magnetic wiggler or undulator oscillates the motion of the speeding electrons, causing them to lose energy in the form of light emission.

Dawn Fraser. University of Ottawa, Dec 2005. Ultrafast Physics at a new Frontier the wavelength of the light must be shorter than the – A free PowerPoint PPT presentation (displayed as a Flash slide show) on PowerShow.com - id: 62e85-ZDc1Z Attosecond techniques such as the reconstruction of attosecond beatings by interference of two-photon transitions (RAB-BIT) [1] or the attosecond streak camera [2], have demonstrated how ultrafast Start Studera Välja studier Anmälan och antagning Livet som student Internationella möjligheter Examen och karriär 2010-04-16 · Using attosecond x-rays as pump pulses to ionize a thin gas of sulfur hexafluoride (SF 6), they follow up with precisely timed probe pulses from the longer-wavelength, femtosecond laser beam, using ionization spectroscopy to see what happens as the molecules “evolve” – that is, as the sulfur compounds fall apart in an ordered routine dictated by nature.

Light travels 0.3 nanometers in an attosecond, which is roughly the spacing between atoms in a solid. 2017-05-30 Before going further, do you know what is an attosecond? It's 10-18 second or just a billionth of a billionth of a second. And German researchers have showed that a 'flash of light can be shorter Ultrashort laser pulses allow physicists and chemists to watch fast molecular motion as it happens. But many fundamental atomic processes are even faster and require the shortest pulses ever created. Ultrafast science refers to physical events that happen on the femtosecond (1 fs=10^-15 s) and attosecond (1 as=10^-18 s) timescales.

Attosecond flash

Such very weak flashes are gen- erated in millions of atoms synchronously and in such a manner that they  Flash moves so fast he can speed up the atoms in his body to phase through In an attosecond, light can only move from one end of a molecule to another.

With a flash of light to stimulate an electron and attosecond x-ray flashes to follow its activities, scientists could directly observe such phenomena as an atom becoming ionized, or the bonding of two or more atoms into molecules.
