attosecond

'Depending on the research, you have this entire field of attosecond pulses.

However, such tunneling times were beyond the experimental reach until recent advances in ultrafast physics have made possible measurements of time in the attosecond scale, opening up the experimental possibility of measuring electronic tunneling times through a classically forbidden region [3-6] and reigniting the discussion of tunneling times.

Using flashes of x-ray radiation lasting only few hundred attoseconds (1 attosecond = 0.000000000000000001 seconds) followed by optical light flashes of similar duration (a tool developed by the group last year) the scientists obtain an ultrafast camera which allowed them to take snapshots of the short-lived excitons in silicon dioxide for the first time.

The selections that make up the main body of the text are devoted to attosecond time-resolved spectroscopy, interfacial charge transfer states in condensed phase systems, recent advances in quantum dynamics of bimolecular reactions, and a great many other related topics.

A team at the Laboratory for Attosecond Physics, which is run jointly by LMU and the MPQ, has now taken an important step towards realising this goal by generating bright beams of hard X-radiation by purely optical means.

(2001) Ponder omotive laser acceleration and focusing in vacuum for generation of attosecond electron bunches.

Newport said that the company's high-precision ultrafast lasers, enable advanced research applications, including the pioneering of attosecond (10-18 second) science to study physical, chemical and biological phenomena at the atomic and subatomic levels.
